1. Fix the problem not the blame.
Often attributed to the Japanese, I first came across it in the movie Rising Son with Sean Connery.
2. Asking forgiveness is easier than asking for permission.
Read Admiral Grace Hopper created this one. Amazing Grace.
3. There are two kinds of fool. One says 'This is old, therefore it is good' and the other says 'This is new, therefore it is better'
Guess I've been all kinds of fools.
