No one lives long enough to learn everything they need to learn starting from scratch. To be successful, we absolutely, positively have to find people who have already paid the price to learn the things that we need to learn to achieve our goals. We never stop investigating. We are never satisfied that we know enough to get by. Every question we answer leads on to another question.
Failure is never fatal.
The bigger you dream, the higher you go. The secret of success is learning how to use pain and pleasure instead of having pain and pleasure use you. If you do that, you're in control of your life. It's a lot of things. It is something you cannot be afraid of, because you will stop growing.
