Instead of finding reasons why you can't, find reasons why you can.

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

Knowledge is of no value unless you put it into practice.

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

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

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

Dreams don't work unless you do.

I can is 100 times more important than IQ.

Skills are built not born.

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

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

There are no shortcuts to any place worth going.

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

The greatest enemy to human potential is your comfort zone

Each day is an opportunity to improve. Aim to be that little bit better than yesterday and better tomorrow than today.
