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

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

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. 

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

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

You'll never change your life until you change something you do daily. The secret to success and change in found in your daily routine.

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

Nothing is impossible if you want it badly enough. Impossible = I'm possible.

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

Good mathematics is not about how many answers you know... It is about how you behave when you don't know.

Practice makes comfort. Expand your experiences regularly so every stretch won't feel like your first.

Hard work - a two way street where you get exactly what you put in.

You can hire a tutor but you can't hire someone to practice for you.

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

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