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

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

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.

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. 

It always seems impossible until it's done.

If you really want something you’ll find a way. If you don’t you’ll find an excuse.

Tough times never last, but tough people do.

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

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

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

There are no shortcuts to any place worth going.

Your attitude is everything. Pick a good one.

Fall down seven times, stand up eight.

The greatest glory in loving lies not in never falling, but in rising every time we fall.

Good mathematics is not about how many answers you know... It is about how you behave when you don't know.
