Don't fear failure, fear being in the same exact same place next year as you are now.

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. 

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

Knowledge is of no value unless you put it into practice.

The easiest person to deceive is yourself.

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

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

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

The greatest enemy to human potential is your comfort zone

The greatest glory in loving lies not in never falling, but in rising every time we fall.

Fall down seven times, stand up eight.

No one starts out on top. You have to work your way up.

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

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