Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.

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

There are no shortcuts to any place worth going.

You cannot escape the responsibility of tomorrow by evading it today

Knowledge is of no value unless you put it into practice.

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.

Procrastination is the thief of time and the enemy of success.

Tough times never last, but tough people do.
