If you could start over again, would you have done things differently?
What would you change and why?

I'd spend more time with family, I'll listen to their stories, I'll make myself understand them.
I'd not hide secrets from my best friend, it hurts both parties.
I'd actually do some serious studying, then I wouldn't be hanging here, unsure of what to do next after high school.
I'd read more, all languages and all genres of books.
I'd want to learn music too, probably piano or guitar.
I'm eighteen and I have zero musical cells in me, I want to change that.
I'd learn to draw, to paint, to colour my world; it'll be a wonderful alternative to express my feelings other than using words.
I'd take up a sport, maybe swimming, maybe badminton.

How about you?  Tell me your story.  :)
