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

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

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

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

I had no time is no excuse. 1 hour is 4% of your day and 1 minute is 0.34 % of your day.

Don't expect to be good at maths or understand things straight away. Be patient and persistent. Rome wasn't built in a day, but they worked on it every single day. 

When you make a mistake, take another chance. Only when you choose not to do so do you fail.

You can pick up a mistake and carry it as a burden,  or you can set it down as use it as a stepping stone to greatness.

Everything you want is on the other side of fear

There are no bad mistakes in maths, only discoveries.

There is no talent here. There is hard work and obsession. You could be anyone if you put in the time.

Time is your friend, impulse is your enemy.

Your limitation - its only your imagination.

You cannot escape the responsibility of tomorrow by evading it today

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