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

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

Procrastination makes easy things hard and hard things harder.

Hard work always pays off - it is not a question of if you will get there, but WHEN you will get there

Dreams don't work unless you do.

Failure is not the opposite of success, it is part of the success.

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

Success is not final, failure is not fatal.  It is the courage to continue that counts.

"I" not them. Be the best version of you.

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. 

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

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

You can have results or excuses, not both

Instead of finding reasons why you can't, find reasons why you can.

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