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.
Just as your car runs more smoothly and requires less energy to go faster and farther when the wheels are in perfect alignment, you perform better when your thoughts, feelings, emotions, goals, and values are in balance.
The difference between a goal-directed individual and someone without goals is like the difference between a Wimbledon champion and a kid batting a tennis ball around on a court with no net, no opponent to bring out the best in him, and no way of keeping score.
We choose to go the moon in this decade and do the other things not because they are easy, but because they are hard, because that goal will serve to organize and measure the best of our energies and skills.
