Studying past sales with the objective of learning is wise . . . stewing about what could have been is not. Stewing is a waste of mental energy that steals opportunities. A sale based on an informed decision that considered the seasonal history, profit margin, cash flow need, cost of storage, and unpredictability of the market is a good sale. Greed says to stew when prices rise later . . . wisdom says to devote mental resources to other endeavors—to something that promises a good return.
