Failure to prepare = preparing to fail

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.

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

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

The journey of a thousand miles begins with one step.

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

We learn more from failure than we do from success.

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

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

Success is the sum of small repeated efforts, day in and day out.

You can hire a tutor but you can't hire someone to practice for you.

We are all maths people : step 1 - do maths and step 2 - be a person. 

The master has failed more times than the beginner has even tried

Tough times never last, but tough people do.

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