Ever been so sure you knew the most efficient way to do a task then been completely mind blown when someone shows you a way better method? I sure as hell have! If you look at humans and what motivates us you soon realize we're nothing more than optimization algorithms... Changing the land and world around us to better suit our way of life.
I urge you to never stop looking for ways to improve yourself, your peers and the world around you. Perhaps that looks different between person to person but the fact remains the same, find yourself a better way!
