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

Your attitude is everything. Pick a good one.

You're not in competition with anyone but yourself. Outdo your past, not other people.

You cannot start the next chapter of your life if you keep re-reading the last one.

If you fail, next time fail better.

If you want to succeed, double your failure rate.

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

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

We learn more from failure than we do from success.

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

The power of reflection is the most powerful skill you’ll learn.

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

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

Everything that happens was once a dream.

You can pick up a mistake and carry it as a burden,  or you can set it down as use it as a stepping stone to greatness.
