The greatest enemy to human potential is your comfort zone

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

The easiest person to deceive is yourself.

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

Twenty years from now you will be more disappointed by the things you didn’t do than the things you did do

The journey of a thousand miles begins with one step. 

I had no time is no excuse. 1 hour is 4% of your day and 1 minute is 0.34 % of your day.

He who has begun his task is half-way done. Have the courage to begin!

The bad news is time flies, the good new is that you're the pilot.

In order to become better than anybody else you must first become better than yourself.

Fall down seven times, stand up eight.

Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.

Whenever you find yourself doubting how far you can go, just remember how far you have come.

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