There are no bad mistakes in maths, only discoveries.

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

Tough times never last, but tough people do.

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.
