Be who you are in every situation.

Don't shoot for something unattainable - completely outside of your nature or opportunity.

One of the main techniques I used was focusing on the goal and visualising myself competing in the race before the race started.

As an athlete, I'd average four hours a day. It doesn't sound like a lot when some people say they're training for 10 hours, but theirs includes lunch, massage and breaks. My four hours was packed with work.

Your problems pale in comparison with those of the millions of people in the world who do not have enough to eat.
