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

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

Don’t be afraid to work hard and find out how good you can really be.

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. 

Success can never happen without the journey (struggle).

Go as far as you can see, when you get there, you’ll be able to see further

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

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

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

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

When you make a mistake, take another chance. Only when you choose not to do so do you fail.

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

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

There is no talent here. There is hard work and obsession. You could be anyone if you put in the time.

Don’t practice until you get it right, practice until you can’t get it wrong.
