The greatest enemy to human potential is your comfort zone

Failure to prepare = preparing to fail

You cannot escape the responsibility of tomorrow by evading it today

Hard work - a two way street where you get exactly what you put in.

The journey of a thousand miles begins with one step. 

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

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

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.

A book a day keeps the stupidity away.

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. 

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

Yesterday is history, tomorrow is a mystery, but today is a gift—that's why it's called 'the present

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

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.
