It takes a lot of courage to release the familiar and seemingly secure, to embrace the new. But there is no real security in what is no longer meaningful. There is more security in the adventurous and exciting, for in movement there is life, and in change there is power. Alan Cohen
What's done is done - William Shakespeare
Shakespeare is talking about acceptance. The facts of the past can never be changed. What we can choose is how we view those facts and whether we allow them to corrupt our future. Whatever happened, you did the best you could, given the knowledge and abilities you had at the time. Tomorrow is a new day. Begin with a fresh outlook that does not project your past into your future.
-Jonathan Lockwood Huie
