Our mistakes make us who we were meant to become, who we wanted to be before we made them. THAT is why men should always be there through the tough times and why, even though emotions overtake them and women get mad, they should stay. That's how little sweet wrinkled hands, perfect little old couples are built. Commitment to allow mistakes to shape us.
What screws us up most in life is the picture in our head of how it's supposed to be. For more quotes and inspirations: http://www.lifehack.org/articles/communication/what-screws-most-life-the-picture.html?ref=ppt10
