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

It is never too late to turn an unproductive day into a productive one.

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

Procrastination makes easy things hard and hard things harder.

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

Don’t compare yourself to others. Compare yourself to the person you were yesterday.

Fall down seven times, stand up eight.

Practice makes comfort. Expand your experiences regularly so every stretch won't feel like your first.

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. 

The bad news is time flies, the good new is that you're the pilot.

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

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

There are no shortcuts to any place worth going.

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