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

If you can understand just one thing thoroughly, then you will understand everything.

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

The boxer is not afraid of being knocked down, he is afraid of not being able to get up again.

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

The bad news is time flies, the good new is that you're the pilot.

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

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

Instead of finding reasons why you can't, find reasons why you can.

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

Failure is NOT your destiny. Failure is the key to success.

We all make mistakes. What matters is how we choose to move forwards from them.

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. 

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

Lose an hour in the morning and you will spend all day looking for it.
