I Don't Have A Problem

The other day my cg leader ask to share what keep us awake at night. But shockingly it is me that can sleep every night very well while the rest of them have something in their heads to think about. Why is that? Is it because I am not normal or am I in a tidak apa attitude or is it I just don't think too much and let my life be simple and be happy with what I have?

How about you guys? Can you sleep well at night?
