Success in any endeavor depends on the degree to which it is an expression of your true self.
My definition of success is to live your life in a way that causes you to feel a ton of pleasure and very little pain - and because of your lifestyle, have the people around you feel a lot more pleasure than they do pain.
Success depends in a very large measure upon individual initiative and exertion, and cannot be achieved except by a dint of hard work.
My definition of success is control.
The first requisite for success is the ability to apply your physical and mental energies to one problem incessantly without growing weary.
Success, in whatever form it takes, is a tricky thing - once you've achieved your goal, then what? Where do you aim?
Your success depends mainly upon what you think of yourself and whether you believe in yourself.
The only true measure of success is the ratio between what we might have done and what we might have been on the one hand, and the thing we have made and the things we have made of ourselves on the other.
Success is a science; if you have the conditions, you get the result.
I don't talk about success. I don't know what it is. Wait until I'm dead.
