Success is not the key to happiness. Happiness is the key to success. If you love what you are doing, you will be successful.
-By Albert Schweitzer
Continuous efforts - not strength or intelligence- is the key to unlocking our potential.
The only limit to our realization of tomorrow will be our doubts of today.
Action is the foundational key to all success.
Success seems to be connected with action. Successful people keep moving. They make mistakes, but they don't quit.
The road to success and the road to failure are almost exactly the same.
