Can anyone achieve any goals?

¡Buen trabajo, Jose! Ojalá que mis correcciones te ayuden =)

i think that not all the people born with skills and because of that, the mayority (majority)has to practice and practice to achieve any goal in the life.

Not all people are born with skills and, because of that, the majority of us have to practice and practice to achieve any goal in life.

me right now i want to speak and think like a native of the English lenguage (language) Every day i gonna practice to dominete (dominate) this beutyfull lenguage (beautiful language).

Right now, I want to speak and think like a native English speaker. I'm gonna practice every day to dominate this beautiful language. 

"Dominate" sounds a little unnatural to me, though. You might want to try something like "master".

I imagine stay (staying) in London, New York or Sidney (Sydney) talking with other people and they ask me if ¿am i a native? Because I speak English very well.

I imagine living in London, New York or Sydney and being asked if I'm native because I speak English so well.

Good luck with your studies! English is a little complicated, but it's so fun! You're off to an amazing start. Keep it up!

Can anyone achieve any goal?

I don't think that all people are born with skills, and because of that the majority have to practice and practice to achieve anything (or: their goals) in life.

Note: 'majority' is a collective noun; it takes 'have' when you are talking about the different members of the majority.

As for me, right now I want to speak and think like a native speaker of English. Every day I'm going to practice in order to master this beautiful language.

(We don't usually use  'gonna' in writing, except in very informal contexts.)

I imagine stay in London, New York or Sydney talking with other people and they ask me if ¿am i a native? Because I speak English very well.

I imagine being in London, New York or Sydney, talking with other people, and they ask me if I am a native speaker because I speak English very well (better: so well).
