Nothing is impossible if you want it badly enough. Impossible = I'm possible.

The greatest enemy to human potential is your comfort zone

Everything you want is on the other side of fear

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

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

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. 

Time is your friend, impulse is your enemy.

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

Fall down seven times, stand up eight.

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

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

Practice makes comfort. Expand your experiences regularly so every stretch won't feel like your first.

Dreams don't work unless you do.

Success is a journey, not a destination.

Procrastination is the thief of time and the enemy of success.
