People often say they want a customized, personalized solution to their problem. They say that because it sounds good, but the reality is that most people want a one-size-fits-all solution.
That’s because a universal solution comes with no blame, guilt, or work. If it works for everyone, then everyone has the problem – my individual effort (or lack thereof) wasn’t the cause. And if it works for everyone, then I won’t have to work especially hard (or at all) for my problem to be solved.
Those kinds of solutions are scams. Solving your unique problems will always require unique effort. Anything else is a con.
