I think, therefore I am.

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

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

Tough times never last, but tough people 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. 

Success is a journey, not a destination.

No one starts out on top. You have to work your way up.

The journey of a thousand miles begins with one step.

Failure to prepare = preparing to fail

It doesn’t matter where you start, it matters how you end

Procrastination makes easy things hard and hard things harder.

Hard work - a two way street where you get exactly what you put in.

If you fail, next time fail better.

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

You can have results or excuses, not both
