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

Procrastination makes easy things hard and hard things harder.

Success can never happen without the journey (struggle).

Tomorrow is worth more than yesterday but less than today.

Work like you don't need the money, dance like nobody's watching and love like you've never been hurt. 

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.

There are no shortcuts to any place worth going.

If you can understand just one thing thoroughly, then you will understand everything.

When you make a mistake, take another chance. Only when you choose not to do so do you fail.

Failure is not the opposite of success, it is part of the success.

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

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

I had no time is no excuse. 1 hour is 4% of your day and 1 minute is 0.34 % of your day.

Do what you have always done and you will always be what you have always been
