The greatest enemy to human potential is your comfort zone

Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.

Time is your friend, impulse is your enemy.

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

Success is not final, failure is not fatal.  It is the courage to continue that counts.

Mistakes have the power to turn you into something better than you were before.

You cannot start the next chapter of your life if you keep re-reading the last one.

You can have results or excuses, not both

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

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

Yesterday is history, tomorrow is a mystery, but today is a gift—that's why it's called 'the present

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

Don’t be afraid to work hard and find out how good you can really be.

Success can never happen without the journey (struggle).

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