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. 

You cannot escape the responsibility of tomorrow by evading it today

Fall down seven times, stand up eight.

A hero is no braver than an ordinary man, but he is braver five minutes longer.

Our fixed mindset builds our cage, fear keeps us in it.

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

There are no bad mistakes in maths, only discoveries.

Tomorrow is worth more than yesterday but less than today.
