I disagree. Iterating your way to finding your one thing is just experimenting in hopes of landing on something. That's possible, but that's more a science project than starting a company. What I'm advocating (from experience) is that you should/must settle on a one thing before you start your company. You can then iterate towards figuring out how to make your one thing work, gain traction, etc., but you need to at least know what the one thing you are trying to do is before you start your company. e.g. just saying "I want to do something in the storage space" isn't enough. You can spend the next 2 years trying a lot of things in the storage space. That's experimenting. But identifying a specific one thing you want to do in the storage space enables you to start a company. Then, you can iterate towards the solution, but you need to start with a specific problem you want to solve.
