Mackay's Moral: If you are persistent, you will get it. If you are consistent, you will keep it.
You're a lot better off being scared than being bored.
You do not get what you want. You get what you negotiate.
When you're thirsty, it's too late to think about digging a well.
Failure is an attitude, not an outcome.
If you get a chance, take it. If it changes your life, let it.
