The road to success is like a staircase. If you want to succeed, double your failure rate

Everything you want is on the other side of fear

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.

The power of reflection is the most powerful skill you’ll learn.

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. 

There are no bad mistakes in maths, only discoveries.

Success is a journey, not a destination.

I have not failed, I've just found 10,000 ways that won't work.

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

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

I can is 100 times more important than IQ.

Time is your friend, impulse is your enemy.

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

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

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