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 are no bad mistakes in maths, only discoveries.

If you want to succeed, double your failure rate.

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

No one starts out on top. You have to work your way up.

Skills are built not born.

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

Work like you don't need the money, dance like nobody's watching and love like you've never been hurt. 

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

The journey of a thousand miles begins with one step.

Success is a journey, not a destination.

Time is your friend, impulse is your enemy.

Fall down seven times, stand up eight.

Never let a dark chapter make you forget that better days are ahead of you. Your story is far from over.
