You may encounter many defeats, but you must not be defeated. In fact, it may be necessary to encounter the defeats, so you can know who you are, what you can rise from, how you can still come out of it.
My fault, my failure, is not in the passions I have, but in my lack of control of them.
If you're not failing every now and again, it's a sign you're not doing anything very innovative.
I have not failed. I've just found 10,000 ways that do not work.
Many of life's failures are people who did not realize how close they were to success when they gave up.
I don't know the key to success, but the key to failure is trying to please everybody.
Ever tried? Ever failed? No matter. Try again. Fail again. Fail better.
There are never failures -- only gained experience, wisdom, knowledge and lessons in life
Success is never final. Failure is never fatal. Courage is what counts.
If at first you don't succeed, try, try again. Then quit. There's no point in being a damn fool about it.
