I can't change the direction of the wind, but I can adjust my sails to always reach my destination.
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 biggest risk is not taking any risk. In a world that is changing quickly, the only strategy that is guaranteed to fail is not taking risks.
The difference between a successful person and others is not a lack of strength, not a lack of knowledge, but rather a lack in will.
Success is not final, failure is not fatal: It is the courage to continue that counts.
