Unfortunately we learn a little late down the path that most things that we worry about and give our utmost intentions to dont really give us comfort . Stopping and putting things in perspective of fond memories and happiness doesnt happen often enough.
The homunculus Greed from Fullmetal Alchemist. I agree with greed. Being greedy doesn't mean u only want money it means u want something that you don't have so everyone is greedy sometimes (or all the time)
