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

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

Success can never happen without the journey (struggle).

Tomorrow is worth more than yesterday but less than today.

If you fail, next time fail better.

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

The easiest person to deceive is yourself.

Pure mathematics is in its way, the poetry of logical ideas.

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

Life is full of opportunities. With every opportunity that is missed, another one is born.

Time is your friend, impulse is your enemy.

Don’t hang your targets after you’re done shooting.

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. 

Focus on progress, not perfection. Practise a little bit every day - little and often  Slow and steady wins the race.

Dreams don't work unless you do.
