"Always look at what you have left.Never look at what you have lost." Robert H. Schuller 

"Holding on to anger is like grasping a hot coal with the intent of throwing it at someone else; you are the one who gets burned. Buddha 

"Finish each day and be done with it. You have done what you could. Some blunders and absurdities no doubt crept in; forget them as soon as you can. Tomorrow is a new day; begin it well and serenely and with too high a spirit to be cumbered with your old nonsense." 

–– Ralph Waldo Emerson 

I'ts not what happens to you that determines how far you will go in life; it is how you handle what happens to you. 

Zig Ziglar
