The greatest enemy to human potential is your comfort zone

Tough times never last, but tough people do.

Success is a journey, not a destination.

Run in the morning before your body figures out what you're doing

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 be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

Procrastination makes easy things hard and hard things harder.

The master has failed more times than the beginner has even tried

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

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

Failure is not the opposite of success, it is part of the success.

Your limitation - its only your imagination.

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

Patience is when you’re supposed to get mad, but you choose to understand

The temptation to quit will be the greatest when you are about to succeed
