There is great wisdom in being able to realise that you don’t understand something before it goes too far.

Pure mathematics is in its way, the poetry of logical ideas.

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

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

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

A hero is no braver than an ordinary man, but he is braver five minutes longer.

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

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

The master has failed more times than the beginner has even tried

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

I have not failed, I've just found 10,000 ways that won't work.

No matter how bad it gets, you’re still way ahead of those who haven’t even started.

Don't expect to be good at maths or understand things straight away. Be patient and persistent. Rome wasn't built in a day, but they worked on it every single day. 

Don't fear failure, fear being in the same exact same place next year as you are now.

Run in the morning before your body figures out what you're doing
