It is weird because I get from the context of your piece that you are in silicon valley and worked on startups. Don’t start a company just because you want to start a company… that’s like dating just for not feeling alone etc. Start with projects that solve a problem. It is simple yet challenging, by starting to do these you will see what are the problems you are truly passionate about and then think of ways (or the skills you need. people, setting etc) you need to solve them.
I started already 2 startup projects, the first one was mildly successful financially and the second one is looking for funding. They are still in a sense projects that brought very passionate people together to solve a country in a straightforward way. Do that in Silicon Valley and watch the results.
