Yeah I do agree. You can sell basically anything. Is just about to use the proper marketing strategy based on price, niche, offer, timing, traffic source and that's it. With proper mental triggers, and knowing the psychology behind the marketing it's about everything. Remember that things like Meta Ads, Google Ads, Bing Ads, TikTok Ads, Landing Pages, etc. are just tools. But the magic happens in the psychology of the humanity that is the same and it will be the same for as long as we will live at least.
