Success is not the key to happiness. Happiness is the key to success. If you love what you are doing, you will be successful.
The greatest glory in living lies not in never falling, but in rising every time we fall.
It's not about money or connections. It's the willingness to outwork and outlearn everyone.
The secret of joy in work is contained in one word – excellence. To know how to do something well is to enjoy it.
It’s not what you do once in a while; it’s what you do day in and day out that makes the difference.

Excellence is not an act but a habit. The things you do the most are the things you will do the best.
