FOMO is a huge problem in the internet age because we have so many options. It is important to be ok with good enough experience, rather than needing the best possible, because that will be different for every person and impossible to predict. Monday morning quarterbacking is always perfect and never helpful going forward.

I use a complex mix of methods for choosing books. r/suggestmeabook, r/fantasy, r/printsf, r/romancebooks, r/yalit, r/horrorlit and r/historicalfiction all provide both a search function which can be used for words like best or favorite, and also the opportunity to request specific suggestions from long time readers.

I also use best of the year articles from reputable newspapers and lists of awardwinning books. I also have a local bookstore with a staff suggestions shelf that keeps me in touch with new releases. i have found some favorites there.
