Deeper understanding/thinking out of the box

I posted this in the investing forum, but was thinking this would be more applicable. I'm curious what books/videos/etc you guys would reccomend to someone looking to further their understanding of equity valuation as it relates to share prices. I feel like I've fallen into the same patterns, models, ways of thinking over time. I've searched the topic on WSO and have already read most of what was reccomended.
Do you have any books that have stuck out to you and/or changed your way of approaching valuations? No book is 'below' me as in too basic. I think for starters I'm going to re-read Mckinsey Valuation and Margin of Safety. I would deff like to pick up something new as well.
