I agree. Your hunger is an incredibly good thing. But you should always be training and stretching If you're interested in some books on technique here's what I've been reading.

A Practical Handbook for the Actor by a bunch of interesting people. It's a practical, repeatable, and analytical way of approaching acting. While it is best practiced in a classroom with a knowledgable instructor, the text is good enough to stand on it's own.

History of the Theatre by Brockett is a longggggg read. But it's detailed and a great perspective on what was happening when in relation to plays. Also you can older editions for way way less.

I'm just now reading Sanford Meisner on Acting and that's been an interesting so far, it has a lot more of a narrative which is enjoyable to read.

Hope any of that helps someone!
