The journey of a thousand miles begins with one step. 

Procrastination makes easy things hard and hard things harder.

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

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

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

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

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

I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.

There are no bad mistakes in maths, only discoveries.

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

Everything you want is on the other side of fear

Knowledge is of no value unless you put it into practice.

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.

Whenever you find yourself doubting how far you can go, just remember how far you have come.
