Love the quotes!
Here are a few that I have hanging around my computer:
"Forget past mistakes, forget failures, forget everything except what you are going to do right now, and just do it."
"The difference between the impossible and the possible, lies in a persons determination."
"Take the first step in faith, you don't have to see the whole staircase, just the first step."
"Life isn't about waiting for the storm to pass, it's about learning to dance in the rain."
"Dripping water can eat through stone."
And my favourite:
"Do the one thing you think you cannot do. Fail at it. Try again. Do better the second time. The only people who never tumble, are those who never mount the high wire. This is your moment, own it."
