more mature

I'm now older
I must think better than yesterday
I must think about my future
not just to waste my time to going useless activity
I learn more about life
I learn about how to solve a problem
I had much experience
But until now I still don't know about my self
I don't know why I'm sad
I don't know why I'm glad
But I still try to help everyone around me
I wanna try to be a useful man
More mature to get the best future
