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

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

I can is 100 times more important than IQ.

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

It is never too late to turn an unproductive day into a productive one.

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.

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

We all make mistakes. What matters is how we choose to move forwards from them.

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

Success is a journey, not a destination.

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. 

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

Success is not final and failure is not fatal. It is the courage to continue that counts.

There is great wisdom in being able to realise that you don’t understand something before it goes too far.
