The power of reflection is the most powerful skill you’ll learn.

Just stick with it, what seems hard now will one day be your warm up.

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.

Fall down seven times, stand up eight.

Each day is an opportunity to improve. Aim to be that little bit better than yesterday and better tomorrow than today.
