EVERY FB group and internet forum has its share of critics, naysayers, chronic doubters and condescending know-it-alls who think that by pointing out fairly-obvious potential pitfalls they are somehow superior in intellect or street smarts. I've never found their smug "advice" paticularly useful and I have zero use for them as a source of information. If you like to listen to them, that's on you. 🙄
Skepticism and overall pessimism duly noted. I prefer to expect GREAT THINGS out of life, as it often leads to those things actually happening. Good luck!
