The road to success is like a staircase. If you want to succeed, double your failure rate

Hard work beats talent when talent doesn't work hard.

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

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.

I think, therefore I am.

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.

There is no elevator to success, you have to take the stairs.

Pure mathematics is in its way, the poetry of logical ideas.

Focus on progress, not perfection. Practise a little bit every day - little and often  Slow and steady wins the race.

The journey of a thousand miles begins with one step. 

The greatest mistake we make is living in constant fear that we will make one.

We learn more from failure than we do from success.

The master has failed more times than the beginner has even tried

It is never too late to turn an unproductive day into a productive one.
