Success is not final, failure is not fatal: It is the courage to continue that counts.
You have within you right now, everything you need to deal with whatever the world can throw at you.
The greatest glory in living lies not in never falling, but in rising every time we fall.
You can't go back and change the beginning, but you can start where you are and change the ending.
Darkness cannot drive out darkness; only light can do that. Hate cannot drive out hate; only love can do that.

Success is not the key to happiness. Happiness is the key to success. If you love what you are doing, you will be successful.
