Yeah, I don't understand those who are sooooo concerned about how others spend their money.
Especially those who have not tried something for themselves in their own set ups. But boy oh boy, do they ever know what is a waste of money to them. And because it's a waste of money to them, it's gotta be a waste of money to everyone. And they don't need to try it, because they just know it's a big scam.
Personally, I reserve judgement on something until I have tried it for myself. And for the most part, I don't have any skin in the game. I just try stuff. If it works, great, if it doesn't, I move on.
Too many are very closed minded, and it's not enough for them to have an opinion about something they have not tried, they need to convince others who have tried, and who found a benefit from whatever the thing is, that they are wrong in their findings.
