Don't aim for success if you want it; just do what you love and believe in, and it will come naturally. 

David Frost 

Develop success from failures. Discouragement and failure are two of the surest stepping stones to success. 

Dale Carnegie 

Take up one idea. Make that one idea your life - think of it, dream of it, live on that idea. Let the brain, muscles, nerves, every part of your body, be full of that idea, and just leave every other idea alone. This is the way to success. 

Swami Vivekananda
