What's Your No. 1 Change?

For me, it was starting First30Days. It was a hard journey leaving the comfort of a secure corporate job to do something that I love and believe makes a difference in the lives of others.

The other day I was wondering why it is so hard for us to celebrate what we have achieved. Maybe we worry that we will be viewed as arrogant? But if you don't celebrate your victories— big, gigantic and small—no one else will.

What change are you most proud of?
