It's easy to see all the useful things I would have missed out on if I worked remotely. Examples:
- Networking: Serendipity plays a bigger role than anything else. And you get a lot less of it the fewer people you interact with. Simply bumping into people at the cafe is quite valuable.
- Career coaching: Lots of classes, talks, invited speakers, etc. Some can be done remotely, but roughly half require you to be live.
Also: Going to work makes it easier to leave work there when you come home.
