> There's always plenty of room for improvement - in your code, in your abilities, in you.

I just saw an amazing movie about a man that embodies this philosophy: "Jiro Dreams of Sushi"[1]. This man's dedication to further mastering his craft is unparalleled. Even though he is widely regarded as the best Sushi chef in the world, he is still singularly focused on becoming better every day.

I highly recommend watching - it's very inspiring.
