You cannot escape the responsibility of tomorrow by evading it today

Procrastination is the thief of time and the enemy of success.

Skills are built not born.

The temptation to quit will be the greatest when you are about to succeed

Everything you want is on the other side of fear

Success is a journey, not a destination.

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

The journey of a thousand miles begins with one step. 

Just stick with it, what seems hard now will one day be your warm up.

Tough times never last, but tough people do.

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

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

There are no shortcuts to any place worth going.

99% of genius comes from hard work, the remaining 1% comes from innate talent

There are no bad mistakes in maths, only discoveries.
