This is when you have an unsatiable appetite, an excessive desire for food and material wealth.
Greed is when you think that your life cannot go on unless you have those 'must-haves' that advertisers dupe you into believing are a necessity.
Therefore develop self-control and self-discipline.
Make a decision not to be swayed by anyone.
Do not act on impulse. Think.
Stand firm or you will fall for anything.
