Education will not: the world is full of educated derelicts. Persistence and determination alone are omnipotent.

I have never pretended to be the best Scientologist, but I openly and vigorously defended the church whenever it was criticized, as I railed against the kind of intolerance that I believed was directed against it. I had my disagreements, but I dealt with them internally.

To ask questions can become the laziest and wobbliest occupation of a mind, but when you must yourself answer the problem that you have posed, you will meditate your question with care and frame it with precision.
