Whenever you find yourself doubting how far you can go, just remember how far you have come.

It is never too late to turn an unproductive day into a productive one.

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.

There are no bad mistakes in maths, only discoveries.

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

I had no time is no excuse. 1 hour is 4% of your day and 1 minute is 0.34 % of your day.

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

It always seems impossible until it's done.

You cannot escape the responsibility of tomorrow by evading it today

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

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

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

Twenty years from now you will be more disappointed by the things you didn’t do than the things you did do

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. 

Hard work always pays off - it is not a question of if you will get there, but WHEN you will get there
