Jealousy is when their reflection in the mirror that is your progress, is attacked rather than appreciated, begrudged rather than understood.

What differentiates humans from all other creatures is the deep and unquenching desire to be appreciated.

Anything great will only be appreciated if I am given the opportunity to feel the absence of it, or experience the reversal of it. It is only then that I can even begin to understand its majesty and cherish it in the manner I should have all along.
