Focus on progress, not perfection. Practise a little bit every day - little and often  Slow and steady wins the race.

The greatest enemy to human potential is your comfort zone

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.

Success is a journey, not a destination.

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

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

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

Never underestimate the importance of small steps. small steps = big changes. 

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

The bad news is time flies, the good new is that you're the pilot.

Time is your friend, impulse is your enemy.

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

Don't expect to be good at maths or understand things straight away. Be patient and persistent. The most powerful warriors are patience and time.

Everything you want is on the other side of fear

I can is 100 times more important than IQ.
