Today, my topic willis "The best book I've ever read"."

Period before quote

So II've read a lot of books, but I've only memorised only one.

"I read" implies that you only did the thing once, so you should add "I have read/I've read"
A lot of books means book should be plural

It is acalled "Atomic habits." I read this book oin Russian language.

When something has a title, you say that it is called [title]
Use in for languages (something is done in a language)

However, I want to read it oin English.

Comma after however

This book is really interesting and useful.

After that book, I became interest oed in psychology and sometimes I'm thinking about become to Ping a psychologiest.

Interested in instead of interest on
To make a verb into a noun, add ing usually (become to becoming)

But I don't have any talent to help another people at all.

Fortunatetly, one of my friends is also interested in psychology, o. Only with him I can I share my emotions about this book.

And what a relifef it was that I read this book in my yong ageuth.

The noun for young age is youth

After that, I started to read many books for my education.

I think that parents or teachers should make books more interesting for children.

For opinions, write that after think
Interest is the noun, interesting is an adjective

In conclusion, I want to say that I recommend this book forto you.

Today my topic will be "The best book I've ever read".

So. I read a lot of books, but I've only memorised only one.

I see someone else corrected your spelling of memorised to memorized, so just pointing out this is a British English vs American English difference. British English uses memorised, while American English uses memorized.

It is a "Atomic hHabits". I read this book oin Russian language.

"Atomic Habits" is a title, so should be title case.

A "book on Russian language" would be a book about the Russian language. "a book in the Russian language" / "a Russian language book" / "a book in Russian" are ways you can describe the language of a book. And when you're describing how you read the book "in Russian" sounds more natural.

However I want to read it oin English.

This book is really interesting and useful.

After that book I became interested on psychology and sometimes I'm thinking about become to Ping a psychologiest.

"sometimes I'm thinking about becoming a psychologist" is a valid phrase you could make, but it's a lot less common and has a lot fewer situations you can use it in.

But I don't have any talent to help another people at all.

"another" doesn't get used with plural nouns.

Fortunatetly one of my friends is also interested in psychology, only with himhe's the only one I can share my emotions about this book with.

You can say "only with him can I" but it's sort of situational and difficult to use right, so I suggest just keeping to "he's the only one I can <...> with" which is a bit simpler.

And what a relifeblessing that I read this book in my young age.

I think relife was meant to be relief, but it's not quite correct phrasing here.

"blessing" is the only single word I can think of that fits here without rewording a lot more of your sentence, but it is is a little bit of an old-fashioned expression

After that I started reading many books for my education.

I think parents or teachers should make books more interesting for children.

In conclusion, I want to say that I recommend this book forto you.
