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

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

Mistakes have the power to turn you into something better than you were before.

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

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.

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

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

No one starts out on top. You have to work your way up.

Procrastination makes easy things hard and hard things harder.

Dreams don't work unless you do.

We learn more from failure than we do from success.

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

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

He who has begun his task is half-way done. Have the courage to begin!
