Many new businesses attempt to fight people’s bad habits (smoking, sloth, overeating, etc.) They think “I’ll help these people and make money!” But, most people truly don’t want change. They actually just want to feel better about not putting in hard work. So, customers buy a product (like a gym membership or running shoes), feel temporarily better and then usually never use it again.
The businesses that succeed versus bad habits recognize this pattern and profit from selling instant gratification and not change. See gym memberships, electronic cigarettes, P90X. If your business involves fighting customers’ bad habits, know you’re really selling immediate gratification — make certain your business model allows you to profit from that.
