First I'd like to start this by saying I think a lot of dating advice has diminishing returns, because there's a lot of luck and timing that involves finding a partner. It's been mentioned on here before but I think Models by Mark Manson is the ultimate healthy guide to dating. I think these chronically online dating coaches don't really succeed in being helpful because ultimately you're going to click with somebody or you're not. There's steps you can do to help yourself "click" with more people but ultimately we're not going to be right for the vast majority of people. This is okay and recognizing that dating is two people connecting instead of a game to be won is very important. Another good read for me, was "no more mr nice guy." The name of the book sounds stupid, but it resonated with me as somebody who has been extremely validation seeking.
