Hope might be a good breakfast, but it makes a very poor dinner

If you fail, next time fail better.

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

Practice like you’ve never won. Perform like you’ve never lost.

The boxer is not afraid of being knocked down, he is afraid of not being able to get up again.

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

If you want to succeed, double your failure rate.

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

Don’t be afraid to work hard and find out how good you can really be.

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. 

Don’t compare yourself to others. Compare yourself to the person you were yesterday.

Success is the sum of small repeated efforts, day in and day out.

Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.

Our fixed mindset builds our cage, fear keeps us in it.

Nothing is impossible if you want it badly enough. Impossible = I'm possible.
