How much is too much? That maybe a way to find out if we have greed. Aim high, have larger vision..what is so different between greed and this vision. Only one, when you are thinking about others benefit or taking them to new heights, curing unknown diseases,or improving technology for everyday life..that is a vision for a better future.
However, when all this thinking and accumulation is focused on yourself only, when it is me , me and me..that is greed. Cure for greed is to fulfill other’s need, take away yourself and replace that one space with others.
