Work like you don't need the money, dance like nobody's watching and love like you've never been hurt. 

Success can never happen without the journey (struggle).

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

You can be shown the path, but only you can make the first step.

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

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

Failure is NOT your destiny. Failure is the key to success.

The temptation to quit will be the greatest when you are about to succeed

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

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

We are all maths people : step 1 - do maths and step 2 - be a person. 

Start, struggle, fail, fix and learn. Repeat.

There are no bad mistakes in maths, only discoveries.

Tomorrow is worth more than yesterday but less than today.

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