The temptation to quit will be the greatest when you are about to succeed

Failure to prepare = preparing to fail

Skills are built not born.

You'll never change your life until you change something you do daily. The secret to success and change in found in your daily routine.

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

Hard work always pays off - it is not a question of if you will get there, but WHEN you will get there

The easiest person to deceive is yourself.

Try and do one thing each day that you would really rather not do.

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. 

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

Everything you want is on the other side of fear

You can have results or excuses, not both

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

Just stick with it, what seems hard now will one day be your warm up.

Don't fear failure, fear being in the same exact same place next year as you are now.
