No matter how bad it gets, you’re still way ahead of those who haven’t even started.

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

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

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

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

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

Fall down seven times, stand up eight.

The journey of a thousand miles begins with one step. 

The road to success is like a staircase. If you want to succeed, double your failure rate

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.

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

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

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

Time is your friend, impulse is your enemy.

Do what you have always done and you will always be what you have always been
