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

The greatest enemy to human potential is your comfort zone

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

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

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

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

If you can understand just one thing thoroughly, then you will understand everything.

You'll never change your life until you change something you do daily. The secret to success and change in found in your daily routine.

Try and do one thing each day that you would really rather not do.

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

Your attitude is everything. Pick a good one.

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

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

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. 

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