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

There are no shortcuts to any place worth going.

Fall down seven times, stand up eight.

Failure to prepare = preparing to fail

Success is the sum of small repeated efforts, day in and day out.

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.

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

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

It is never too late to turn an unproductive day into a productive one.

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

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

Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.

It is never too late to become what you might have been

Success can never happen without the journey (struggle).
