Quote from traderjoePerhaps we should indulge in the little and materialistic things and keep us happy.
With every action we take, we can either contribute something to the world or we can take away from it. At the same time, that action will give us either positive feelings or negative feelings. The feelings that we have and the memories that we form are internal to ourselves, and cannot be projected to the outside world except through the actions we take. When we die, our feelings and memories cease to exist, as we lack the physical capability to project them into the world through our actions. The physical consequences of the actions we took while alive will persist for the duration of the existence of the universe.
