Maybe he just likes building things that others find useful.

When I was younger I rented furniture from a company called CORT. I happened to notice on the contract or receipt or something, that it was a Berkshire company (I didn't know that before then).

If I were Warren Buffet, I would have been happy to know that someone was a satisfied customer of one of his companies. I got some decent furniture for a few months at a reasonable price.

Just like I'm happy when someone is a satisfied user of my software.

What has he built

		That's not entirely fair, he may have been profit chasing or he may have actually believed in the companies he was investing in. If he believed in them as an investor he helped build the companies.
