Sometimes we yearn for the old days, when life was so much simpler:
You only need two tools in life - WD-40 and Duct Tape. If it doesn't move and should, use the WD-40. If it shouldn't move and does, use the duct tape.
There must be an equivalent rule for entrepreneurs, such as a sales and marketing equivalent to WD-40 to "move" product, and the marketing and customer service equivalent to duct tape to retain customers. Hmmm.
Maybe that is what Duct Tape Marketing is really supposed to be all about?
