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.

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

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

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

I can is 100 times more important than IQ.

There are no bad mistakes in maths, only discoveries.

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.

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

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

Time is your friend, impulse is your enemy.

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

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

Everything you want is on the other side of fear

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

The journey of a thousand miles begins with one step.
