Hi, I'm William.

I'm an investor and builder based in Australia. By day I think about businesses and what makes them durable; the rest of the time I'm building small things, reading widely, and trying to pass the good habits on to my kids.

This site is my filing cabinet in public: essays on investing and building, summaries of the books that stuck, and the activities and lessons I put together for my children. If something here is useful to you or yours, it's doing its job.
