If you want a good continuation, check out Jordan Peterson, who has a much wider framework into which TLP's somewhat narrow worldview can be fitted. He is also a practicing clinical psychologist, as well as a professor. This video summarises a lot of his ideas, but they are fully explained and justified in his university courses, which are all on the channel. "Personality" is a first year course, and "Maps of Meaning" is I think taken by third or fourth year psychology students.

(You're probably best off ignoring the culture war drama he's currently embroiled in. Unfortunately the youtube algorithm has now placed him firmly in the alt-right nexus because of this, so his videos might shit up your reccommendations. This is not a reflection of his ideas, far from it.)
