We all have two lives. The second begins when we realise we only have one. 

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

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

Don’t be afraid to work hard and find out how good you can really be.

Everything that happens was once a dream.

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

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

Your attitude is everything. Pick a good one.

When you make a mistake, take another chance. Only when you choose not to do so do you fail.

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.

A book a day keeps the stupidity away.

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

Hard work beats talent when talent doesn't work hard.

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

Mathematics Is not a spectator sport. The only way to learn mathematics is to do mathematics.
