how to prepare future life?

I'm doubtful in preparing for my future life.
"What am I going to do after high school?"
"Am I going to work?"
are some of the questions which usually come up inside a teenager's mind XD

So.. Now, I want to prepare for my future life.

1. Decide my goals based on my ability and capability. I have to be clear about what I want in life.

2. Be confident with what I have chosen.

and the last,

3. Having conversation (consult) with my parents. They are the people who know me very well.

Wish me luck, guys n_n
