I think, therefore I am.

Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.

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. 

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

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

No one starts out on top. You have to work your way up.

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

The bad news is time flies, the good new is that you're the pilot.

Lose an hour in the morning and you will spend all day looking for it.

"I" not them. Be the best version of you.

Go as far as you can see, when you get there, you’ll be able to see further

You can pick up a mistake and carry it as a burden,  or you can set it down as use it as a stepping stone to greatness.

If you can understand just one thing thoroughly, then you will understand everything.

Your attitude is everything. Pick a good one.

There are no bad mistakes in maths, only discoveries.
