Don't Knock It Until You Try It? Nah.
Personal experience is "sample size of one". It is noise. It subject to sunk cost fallacy, subjective validation, self-superiority bias, confirmation bias, and all the other cognitive biases. Mankind invented science and scientific process to counteract such biases. Personal observation is subjective, and therefore biased information. Advocating one to "try it" simply proves nothing.
Yet MLMers love to fly this particular argument. They value personal experience over all others, the exactly opposite of scientific process trying to filter out bad data. It is basically fully faith-based.
I was skeptical until I tried it
A true skeptic would know NOT to try it due to all the reason discussed above. The proper way to evaluate something is through scientific and statistical process from a large sample set, not through a single subjective personal experience.
Falling for a dare / lure to "try it" just makes you gullible, not skeptical. Yet MLMers selling nutritional supplements or unproven "treatments" love to fly this particular argument. (also see "What's the harm" below)
I know it works, because it worked for me
So somehow, you're God, and what you experienced is the universal truth for everybody, eh? It's just your subjective experience, based on your circumstances at the time, and based on all your PRIOR memory and experiences. If any one else had different life history, experienced the same thing at a different time, under different circumstances, or any combination of such, the experience will be different.
What you experienced is only good for yourself. It is not a data point. It is anecdote.
