The power of reflection is the most powerful skill you’ll learn.

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

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.

There are no bad mistakes in maths, only discoveries.

The road to success is like a staircase. If you want to succeed, double your failure rate

Never underestimate the importance of small steps. small steps = big changes. 

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

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

You cannot escape the responsibility of tomorrow by evading it today

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

It doesn’t matter where you start, it matters how you end

Practice makes comfort. Expand your experiences regularly so every stretch won't feel like your first.

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

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

I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.
