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 are no shortcuts to any place worth going.

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

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.

The temptation to quit will be the greatest when you are about to succeed

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

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

1.00³⁶⁵=1 and 1.01³⁶⁵=37.7. Doing nothing at all versus small steps at a time.

He who has begun his task is half-way done. Have the courage to begin!

Don't fear failure, fear being in the same exact same place next year as you are now.

There is no talent here. There is hard work and obsession. You could be anyone if you put in the time.

Dreams don't work unless you do.

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