Situation

I think I am very good poker player but I don't have bankroll, I win small and lose it next morning,lol how i gonna make much

You need to have at least some bankroll to begin with like even just $50-100, and then you also need to follow bankroll management. Meaning that with a bankroll this small you only play 2NL cash games or up to $1 tournaments, until it has grown. Best of luck.
