My pPool pParty

I've been studying a lot of subjects and skills, one, two of which isare programming and building.

"Skills" sounds a little odd, because you don't "study" skills.

But my principal point is to communicate with youthe main thing I want to talk about is my birthday and pool party.

What you had written before was correct but super formal. It didn't seem to flow with the rest your essay.

I decided not to go to the army,; instead my mind has requested me for a big andis telling me that having a big, funny party would be better.

I would invite manytons of girls and friends to athis mind-blowing event.

"Tons of" is more colloquial and flows better here.

The problem is I don´'t have enough cash to finance this evenit.

Using "event" two sentences in a row sounds a bit repetitive.

I would be ashamed if people paid for entrance, but it is not an action that an anfitrionhad to pay to get in. That's not something that a host should do.

When you say "but," the two clauses should contradict each other, but they agreed with each other. This flows much better.

"Paid for entrance" is very formal, but it's correct; "had to pay to get in" is much more idiomatic and natural sounding.

However, the high cost may force me to cancel the party, and I'll hadve to makhave a little, poorcheap, boring house party instead.

I've been studying a lot of subjects and skills, onsome of which isare programming and building ["building" as in "construction"?].

When talking about multiple things, we would use something like "some of which are" instead of "one of which is". Otherwise, it implies you are talking about just one thing.

Also, "building" is a pretty general term. If you mean "building" as in the study of building massive, physical structures like houses, skyscrapers, factories, etc, I would use the term "construction".

But my principalmain point is to communicate withtell you about my birthday and pool party.

"principal" is a kind of fancy word here. Here, it's far more natural to say "main point".

"communicate with" is very formal and sounds strange here. I would simply replace "communicate with" with "tell", which is much more natural.

I've decided not to go to the army, i. Instead my mind has requested me for, I'm thinking of having a big and funny party.

"I decided" works, but feels a little odd. "I decided" feels like it happened long ago. However, "I've decided" feels like it happened in the past, but RECENTLY in the past. It feels more natural to use "I've decided" instead of "I decided" in this context.

"My mind has requested me for" is a very odd phrase that's difficult for me to understand. I've replaced it with "I'm thinking of having", though that might not be exactly how you meant to say this.

"Funny" is an adjective I'd use to describe something that is full of jokes and comedic gags. Or, more negatively, it could be used to describe something that is off, like "Hmm, this leftover fish in the fridge smells funny. How long has this been sitting in here?"
I'm pretty sure you actually mean "fun". "Fun" is both a noun and an adjective: something fun makes you have fun.

I would invite many girls and friends to athis mind-blowing event.

"a" instead wrong, but we could also use "the" or "this", which just feel a little more natural to me in this context.

The problem is, I don´t have enough cash to finance this event.

"to finance", yet again, isn't wrong at all, but it sounds very formal. I'd use this if I were trying to start a business, or doing a very big and serious project. If you don't mean to be formal, I'd say "...to pay for this event."

Also, you could say "money" instead of "cash". I almost always say "money" instead for some reason.

I would be ashamed if people paidhad to pay for entrance, but it is not an action that an anfitrion. It's not something that a host should do.

"had to pay" feels more natural than "paid" in this context, though either are still correct.

"but" implies that the next clause contradicts the last, but these two clauses don't. I've decided to make them two separate sentences instead.

"Anfitrion" isn't actually an English word. I know the Spanish word "anfitrión", which in English is "host".

However, the high cost mayight cancel the party, and I hadmight have to make a little, poor, boring house party.

I would use "I had" if this is something that HAS happened. However, we are talking about a theoretical situation that hasn't happened, but MIGHT. So it would be "may have" or "might have".

Speaking of, you can also say "might" instead of "may". Technically, there's a grammatical distinction between them, but both sound perfectly fine to me. I usually prefer "might" over "may".

I've been studying a lot of subjects and skills, onetwo of which isare programming and building.

"subjects and skills" ends up being a little redundant. Programming and building are 2 skills, not 1.

But my principal point is to communicate withtoday, my main point is to tell you about my birthday and pool party.

Principal point is a little too academic in tone for this kind of post.

I decided not to go to the army, instead my mind has requested me forI want to host a big and funny party.

"my mind has requested me" isn't a phrase in English. The closest would be "A thought came to me", but in this case since you're talking about your desires, it's better to be plainer.

I wouldant to invite many girls and friends to a mind-blowing event.

The problem is I don´t have enough (cash to pay for / money to finance) this event.

Cash is very casual and finance is formal, so they don't sound good together. It's better to either use "pay for" as an informal alternative to "finance", or "money" as a less casual term than cash to avoid the mixed tone.

I would be ashamed if people paid for entrance, but it is not an action that an (anfitrion - ?) should do.

Not sure what anfitrion is meant to be. There's probably a better word than action here too, but without knowing what perspective you're talking about, I can't really suggest one.

However, the high cost may cancelprevent the party, and I had to makewould have to make do with a little, poor, boring house party.

"cancel" implies they're already concrete plans, as if you'd sent out a date and time to people already and have to retract it. If it's just an idea currently, "prevent" makes more sense I think.

"had" is past tense, but you're talking more about a hypothetical future, so "would have" is better here.

I could deal with that, but I want this party to happen.

"this" on its own is a little ambiguous here, better to specify.

I've been studying a lot of subjects and skills, onsome of which isare programming and building.

"one of which" doesn't makes sense when you list 2 things ("programming and building"). Also, when listing multiple things, you should use "are" instead of "is".

But my principal point is to communicate withtell you about my birthday and pool party.

"communicate with you" sounds a little bit weird in this context.

I decided not to go to the army, instead my mind has requested me forand now I can't stop thinking about a big and funny party.

With how the sentence is stated, "not going to the army" and "thinking about a big and fun party" can't be contrasted, which means that using "instead" doesn't make sense.

The problem is, I don´t have enough cash to finance this event.

I would be ashamed if people paidhad to pay for entrance, but it is not an action that an anfitrionsomething that a host should do.

However, the high cost may cancel the party, and I had to make a little, poor,so I would have to make a small, cheap, and boring house party instead.

I've been studying a lot of subjects and skills, one of which isincluding programming and building.

Since you mentioned two things here, the words "one of which" will not work in this sentence.

But my principalMy main point is to communicate with you about my birthday and pool party.

Try not to start a sentence with the word 'but.'
'Principle point' usually refers to an idea you want to discuss.

I decided not to go to the army, instead my mind has requested me forI wanted to host a big and funny party.

I would be ashamed if people paid for entrance, but it is not an action that an anfitrionsomething that a host should do.

However, the high cost may cancel the party, and I had to make a little, poor, boringwould have to host a boring, little house party.

'would' is used to speak about a possible future that can happen.
Sounds better to write 'boring, little' instead of 'little, boring'. Makes the sentence flow better.

I could deal with that, but I don't really want thiso.
