We learn more from failure than we do from success.

The greatest glory in loving lies not in never falling, but in rising every time we fall.

I have not failed, I've just found 10,000 ways that won't work.

I think, therefore I am.

Time is your friend, impulse is your enemy.

Do what you have always done and you will always be what you have always been

Don’t compare yourself to others. Compare yourself to the person you were yesterday.

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

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

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. 

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

Whenever you find yourself doubting how far you can go, just remember how far you have come.

If you really want something you’ll find a way. If you don’t you’ll find an excuse.

Everything you want is on the other side of fear

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