Whenever you find yourself doubting how far you can go, just remember how far you have come.

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

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

Practice like you’ve never won. Perform like you’ve never lost.

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

There is no talent here. There is hard work and obsession. You could be anyone if you put in the time.

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

I had no time is no excuse. 1 hour is 4% of your day and 1 minute is 0.34 % of your day.

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

Time is your friend, impulse is your enemy.

We learn more from failure than we do from success.

Tough times never last, but tough people do.

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

Tomorrow is worth more than yesterday but less than today.

If you want to succeed, double your failure rate.
