Success is not final, failure is not fatal: It is the courage to continue that counts.
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 first step towards getting somewhere is to decide that you are not going to stay where you are.
The only way to do great work is to love what you do. If you haven't found it yet, keep looking. Don't settle.
