I would also add to the list some Neal Stephenson books, they're more sci-fi and cover some really out there ideas, but they go really in depth with some business concepts. They even predicted things like crypto-coins, VR, and there's still a lot of stuff in there that can get the gears in motion if you're looking for business ventures. Personal favorites: Snow Crash, The Diamond Age, Interface and Cryptonomicon.

And while the Art of War does cover aspects of leadership, recommending it for anything other than warfare always struck me as a bit strange, since it is a literal manual for feudal combat tactics. It's got chapters on the proper way of making encampments so that they're not overrun by the enemy, not in the "oh, this applies to everything" scenario, but in "use the terrain to guard your back" scenario. Or bits like "if you see the enemy gathering water, and the ones gathering the water are the first to drink, the army is suffering of thirst and stopping them will harm the enemy greatly".
