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

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

Everything you want is on the other side of fear

Knowledge is of no value unless you put it into practice.

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

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

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.

If you can understand just one thing thoroughly, then you will understand everything.

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

We learn more from failure than we do from success.

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

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

Don’t practice until you get it right, practice until you can’t get it wrong.

You can have results or excuses, not both

Life is full of opportunities. With every opportunity that is missed, another one is born.
