The important skill

I think that it's important for a person who should learns a skill in order to be successful in the world.
that is to find something in which you can be interesting or to find an aspiration you can devoted himself to .
when i do some jobs or things i don't like,i may be feel bad.So i can't was attracted to it for a long time.
Certainly,i can't successful in the thing.
For example, Bill Cates like to program.when he was young,he alway though about computer and wrote large number of programs.
He devote himself to computer and interesting in it,so,i think the thing which i talk about before is very important.
Alought the disinterstedness things feel bad to you ,you can still try to find interesting things in it.
This is maybe another important skill.
