Actually, it's not that simple. I know what you're talking about here (I've been through, what, six startups now, including a previous bootstrap?), but it doesn't seem to be quite as essential for me.

There are certainly benefits to that sort of formality, but it's mostly a tactic for a higher-level purpose: maintaining some boundary between Work and Life. As it turns out, I'm mostly handling that in other ways, so far with reasonable success.

Frankly, what I'm wearing matters *far* less than whether I'm in the same room as my computer. Leaving my study and *staying out of it* in the evening is the most crucial part, which will be the long-term sanity challenge...
