Did I took the wrong step?

All along, I've been searching.
Searching for what I really want in my life.
I'm worried.
Worried bout my future.
I study hard, attained good results.
But so what?
Haiz.

Did I chosed the wrong course?
Engineering is really a subject that is freaking hard to learn.
Alvin ah, 19 years old already.
You see how many friends you have already have their goals.
What about you.

You are just....just....
freaking useless.
