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. 

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

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

The greatest enemy to human potential is your comfort zone

There are no bad mistakes in maths, only discoveries.

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

I have not failed, I've just found 10,000 ways that won't work.

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

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

Success is not final, failure is not fatal.  It is the courage to continue that counts.

Success is not final and failure is not fatal. It is the courage to continue that counts.

Your attitude is everything. Pick a good one.

Practice like you’ve never won. Perform like you’ve never lost.

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

We all have two lives. The second begins when we realise we only have one.
