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

Time is your friend, impulse is your enemy.

Dreams don't work unless you do.

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

The greatest mistake we make is living in constant fear that we will make one.

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

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

Don’t practice until you get it right, practice until you can’t get it wrong.

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

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

Failure is NOT your destiny. Failure is the key to success.

The journey of a thousand miles begins with one step. 

Just stick with it, what seems hard now will one day be your warm up.

Mathematics Is not a spectator sport. The only way to learn mathematics is to do mathematics.

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.
