It is never too late to become what you might have been

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

Tough times never last, but tough people do.

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

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

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

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

Dreams don't work unless you do.

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

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

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

Fall down seven times, stand up eight.

You cannot start the next chapter of your life if you keep re-reading the last one.

You can be shown the path, but only you can make the first step.

Mistakes have the power to turn you into something better than you were before.
