The temptation to quit will be the greatest when you are about to succeed

Mathematics Is not a spectator sport. The only way to learn mathematics is to do mathematics.

Focus on progress, not perfection. Practise a little bit every day - little and often  Slow and steady wins the race.

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

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

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.

Never let a dark chapter make you forget that better days are ahead of you. Your story is far from over.

Patience is when you’re supposed to get mad, but you choose to understand

Success can never happen without the journey (struggle).

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

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

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

If you fail, next time fail better.
