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.

We learn more from failure than we do from success.

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

I think, therefore I am.

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.

A hero is no braver than an ordinary man, but he is braver five minutes longer.

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. 

You cannot escape the responsibility of tomorrow by evading it today

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

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

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

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

Everything you want is on the other side of fear

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

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