Am I too demanding?

A typical question that I have always ask myself. A lot of friends told me that I am way too demanding compared to the other girls. I got my strong principal and I will always stick on it no matter what. This brings pros and cons to my life. And I found the cons are always go far beyond the pros. I was used to think everyone should lives in their own way and that is what I always do but things had changed as I growth. This theory should no longer exist. and It's about time to change.
