Recommend me nonfiction that’s actually actionable, not just motivational. I want practical frameworks I can implement tomorrow, not feel-good quotes.

I'm drowning in business/self-help books that are 90% inspiration and 10% substance. I want books that give me actual systems, step-by-step processes, or frameworks I can immediately put to work. Think less Tony Robbins energy, more operations manual.

PS: If you can tell me the ONE specific thing you took from the book and how you applied it, even better.
