I ran into this content on LinkedIn that is an awesome story of a successful searcher from HBS.
Her outcome is rare (100% debt-based), but the things she went through are absolutely normal.
Great learnings, though I'd argue with the "no real industry specification" part of the conversation.
One of the most real quotes: "Harvard [Business School] is very corporate. They don't teach you how to look at a commercial window washing business and evaluate their financials to see if you want to buy it.
They're looking at very complicated financial models, which these are not at all."
