A hero is no braver than an ordinary man, but he is braver five minutes longer.

Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.

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

I think, therefore I am.

We are all maths people : step 1 - do maths and step 2 - be a person. 

Run in the morning before your body figures out what you're doing

The greatest glory in loving lies not in never falling, but in rising every time we fall.

Fall down seven times, stand up eight.

Success is the sum of small repeated efforts, day in and day out.

Success is a journey, not a destination.

You can hire a tutor but you can't hire someone to practice for you.

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

Try and do one thing each day that you would really rather not do.

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

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