I've always taken that quote to mean setting one's mind to put in the work necessary to accomplish anything an individual wants to do. Talking & dreaming doesn't bring an abundance of anything. Gotta put in work to make it happen. There's a point at which one has enough. Eat enough food & one is full. Being greedy & overeating makes a person sick. Lust can lead to degenerate behavior. IMO, greed & lust are negative extremes of human desire when a person is willing to bring hurt, harm or danger to others in their pursuit of weslth, material possessions &/or human affection. Also IMO, a wise & content person knows when they have everything they need to live comfortably in peace, joy & happiness.😎
