As a newbie myself, who has experienced LDs and WILDs thought my own trial and error, I'd say go with learning how to recognize LDs through reality checks, and dream recall with dream journals, becuase those are the two techniques I never learned on my own that I'm trying to learn now that I've read about them. WILDing is a life-altering experience, but if you try too hard to get there, it's just a lot of frustration. I'd say start with the basics, and hopefully the rest will follow naturally. I'm doing it the f-ed up backwards, home-schooled way.
