Among the many speeches he has given in the past, is the video below during which he explains Six Rules of Success - which are excellent tips for people who are exercising and seeking to accomplish a specific goal.
The Six Tips are:
#1. Trust yourself. Follow your own instincts.
#2. Break the rules. Be a Maverick. Don't break the law, but don't be afraid to break the rules and try something new.
#3. Don't be afraid to fail. Failing is okay. It is quitting that is wrong.
#4. Don't listen to naysayers. Because if you only ever listen to negative ideas, you will never accomplish anything.
#5. Work your butt off. Because nobody ever accomplished anything by being lazy / doing nothing.
#6. Find time to give something back. To your community, to society, to your chosen sport or activity.
