Here are three YT channels I follow. Good education, I don’t follow all (or perhaps even many) of the recommendations; I use them for general learning. Note I just linked to recent videos to identify the channel, not because there was anything particularly great in the video.
Everything Money: I like his analytic approach, but the subjective parts are of course the hard part. What growth rates can we reasonably project?
Viktoriya Media: again a good analytic approach and easy to watch.
James Canole: For general retirement planning this is the best I’ve found
Look through these channels to see if there are any videos you like, @Sedan_Clan and also note some of the data sources etc they mention.
