Hard work - a two way street where you get exactly what you put in.

Just stick with it, what seems hard now will one day be your warm up.

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

Good mathematics is not about how many answers you know... It is about how you behave when you don't know.

99% of genius comes from hard work, the remaining 1% comes from innate talent

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

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

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

It is never too late to turn an unproductive day into a productive one.

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

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

The greatest enemy to human potential is your comfort zone

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.

The journey of a thousand miles begins with one step. 

Failure to prepare = preparing to fail
