The greatest enemy to human potential is your comfort zone

You cannot escape the responsibility of tomorrow by evading it today

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

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

It doesn’t matter where you start, it matters how you end

Fall down seven times, stand up eight.

Success can never happen without the journey (struggle).

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

Your attitude is everything. Pick a good one.

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

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

When you make a mistake, take another chance. Only when you choose not to do so do you fail.

We all make mistakes. What matters is how we choose to move forwards from them.

Hard work beats talent when talent doesn't work hard.

No matter how bad it gets, you’re still way ahead of those who haven’t even started.
