One thing has to do with the money that some of us experience and I'm going to use a medical term for it, actually, a psychological or psychiatric term as a metaphor for this, I call it binging and purging with money. You and I can have a relationship with money that really has all the earmarks of food addiction with all the highs and the lows of spending and handling cash.
People who experience feast or famine with money, many of those are people who earn commissions in life.
