Failure to prepare = preparing to fail

You cannot escape the responsibility of tomorrow by evading it today

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

Each day is an opportunity to improve. Aim to be that little bit better than yesterday and better tomorrow than today.

Skills are built not born.

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

Work like you don't need the money, dance like nobody's watching and love like you've never been hurt. 

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

You can have results or excuses, not both

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

Procrastination is the thief of time and the enemy of success.

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. 

The greatest enemy to human potential is your comfort zone

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

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