Good mathematics is not about how many answers you know... It is about how you behave when you don't know.

Hard work - a two way street where you get exactly what you put in.

Don’t hang your targets after you’re done shooting.

We all have two lives. The second begins when we realise we only have one. 

Success is not final and failure is not fatal. It is the courage to continue that counts.

We learn more from failure than we do from success.

Don't fear failure, fear being in the same exact same place next year as you are now.

Don’t confuse your path with your destination. Just because its stormy now doesn’t mean you are headed for failure.

You're not in competition with anyone but yourself. Outdo your past, not other people.

Nothing is impossible if you want it badly enough. Impossible = I'm possible.

Life is full of opportunities. With every opportunity that is missed, another one is born.

99% of failures come from people who have the habit of making excuses.
