There are four powers: memory and intellect, desire and covetousness. The two first are mental and the others sensual. The three senses sight, hearing, and smell cannot well be prevented; touch and taste not at all.

I have far more respect for the person with a single idea who gets there than for the person with a thousand ideas who does nothing.

The man with a new idea is a Crank until the idea succeeds.

If at first the idea is not absurd, then there is no hope for it.

I am reminded of a lady of about my age who was asked by an earnest, little granddaughter the other day 'Granny, can you remember the Stone Age?' Whilst that may be going a bit far, the older generation are able to give a sense of context as well as the wisdom of experience which can be invaluable.

Experience taught me a few things. One is to listen to your gut, no matter how good something sounds on paper. The second is that you're generally better off sticking with what you know.
