As an add-on to this, some people are inherently better at meditation to start with. So hearing from other people how short their journey was from “meditation is just a waste of time” to “after some practice it started to be more effective” can be really discouraging for people where that journey can be years. But everyone can get good at meditating. And generally, the harder or more useless it seems to start out, the more you need what it offers.
