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. 

I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.

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

Everything you want is on the other side of fear

Skills are built not born.

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

Success can never happen without the journey (struggle).

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

Pure mathematics is in its way, the poetry of logical ideas.

Failure is not the opposite of success, it is part of the success.

Do Not Be Afraid To Make Mistakes. Each mistake teaches us something.

Success is a journey, not a destination.

It doesn’t matter where you start, it matters how you end

Hope might be a good breakfast, but it makes a very poor dinner

If you want to succeed, double your failure rate.
