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

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

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.

Don’t compare yourself to others. Compare yourself to the person you were yesterday.

You cannot start the next chapter of your life if you keep re-reading the last one.

A book a day keeps the stupidity away.

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

The wise person knows that no answer is also an answer

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