I believed that people who work harder and try to make an effort to achieve their goal, theys will be successful.

However, the fact lookat is not so easy I imagined.

At fFirst, entrepreneurs have to have a great ambition.

The sSecondly, they shouldn't give up on their goals easily, even thoughif they face on many obstacles.

Some successful people say that you never give upshould never stop working towards your dream until you are successful.

If you say "to give up", it won't make sense when you are talking about being successful, since if you have succeeded you have simply stopped.

That might be true, but it is so difficult to do, because they havone never knowns when theira dream will come true.

What do you mean by "because they have never known when their dream come true"? Do you mean because you never know, or "one" never knows? Then it should be: "That might be true, but it is so difficult to do, because one never knows when a dream will come true." or: "That might be true, but it is so difficult to do, because you never know when your dream will come true."

So that is one of divinethe major tests.

What do you mean by "divine"? "Major", perhaps? Divine specifically means "having to do with god(s)", but it is sometimes metaphorically used.

The next is that they have to look around with their sharp-eyed whether there is any chance near themkeep a sharp/keen eye out for any opportunities.

"Near them" is implied and not needed. "Opportunities" is better to say if it is something like making money or gaining some advantage, like education.

They should firmly believe in their sense and inspiration deeplymselves.

What you wrote is not technically wrong, but I think sounds strange in English. I recommend something like: "You need to firmly believe in yourself" or "They should firmly believe in themselves."

Or, maybe " to trust one's intuition" is better? It means to "trust one's gut/feeling" in this case.

Once they fseel that this might be what they want, they an opportunity, they need to act immediately need to take an action for owning or takingdvantage of it, even if youthey have to sacrifice something.

I hope everybody can complete their goals for being happy and satisfied with our lives, including me.
