You're not in competition with anyone but yourself. Outdo your past, not other people.

Don’t confuse your path with your destination. Just because its stormy now doesn’t mean you are headed for failure.

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

Shoot for the moon and even if you miss you’ll land among the stars/

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 not final, failure is not fatal.  It is the courage to continue that counts.

If you really want something you’ll find a way. If you don’t you’ll find an excuse.

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

Fall down seven times, stand up eight.

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

There are no bad mistakes in maths, only discoveries.

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

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

I think, therefore I am.

Your attitude is everything. Pick a good one.
