Follow the advice of the hedge fund people in other comments. Richer, Wiser, Happier by William Green was a good book. It talks about investing longterm. Having a very long time horizon as you do is a considerable advantage. The other main message I got was that (successful) stock pickers expend a stupendous amount of effort to understand and select stocks. And I will never be able to come close to this effort. So either I just don’t, or if I really want to have a few discretionary stock picks, copy what they do (eg https://whalewisdom.com https://whalewisdom.com).
