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. 

There is no elevator to success, you have to take the stairs.

The greatest enemy to human potential is your comfort zone

We learn more from failure than we do from success.

Run in the morning before your body figures out what you're doing

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

Skills are built not born.

Tough times never last, but tough people do.

Success is a journey, not a destination.

Fall down seven times, stand up eight.

Dreams don't work unless you do.

The master has failed more times than the beginner has even tried

You cannot escape the responsibility of tomorrow by evading it today

There is great wisdom in being able to realise that you don’t understand something before it goes too far.

Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.
