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

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. 

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

Everything you want is on the other side of fear

Just stick with it, what seems hard now will one day be your warm up.

It is never too late to become what you might have been

Tough times never last, but tough people do.

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

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

Procrastination is the thief of time and the enemy of success.

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

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.

Don’t confuse your path with your destination. Just because its stormy now doesn’t mean you are headed for failure.

In order to become better than anybody else you must first become better than yourself.
