Ask HN: How to fight doomscrolling habits with RSS?

I know many HN users love RSS, but I never used it. However, I'm annoyed by myself for doomscrolling too much (mosly those fucked up YouTube Shorts and News Landing Pages) and thought that I want to limit the content I consume to self-selected stuff. Does anyone have good resources for an absolute RSS noob where to start? How did you start? are there different approaches to RSS? what is good RSS software?
