Ask HN: Best book/resources on business modelling?

There's nothing too complicated about it - my father taught me most of this by osmosis before I even graduated from high school because he's come home and talk about all the things he did (he was a business unit director - a business unit he founded after years in engineering sales) and the political intrigue that came with it. My MBA was marginally useful - the biggest value was the paper of the diploma which small minds think is important. I learned 90% of the knowledge before I stepped foot into my first MBA course from working in industry and from my father.

The one added thing: accounting is really important because everything you do as an entrepreneur generally begins and ends with accounting. All your projections and costing built into your pitch deck are derived from accounting specifically income statements. My MBA mostly cemented my accounting knowledge and my ability to use Excel to its corners (99.99% of accounting and finance uses Excel).
