Why I wear the same shirt every day

"[on Steve Jobs] He wore that famous black mock turtleneck ... not to make a fashion statement"

If you hire Issey Miyake to make a custom turtleneck, then you are making a fashion statement. Also, he wore black for a reason - it's a sophisticated, serious, and confident color (or lack thereof) - which was a fashion statement.

Does that apply to my of $2 black Gildan cotton t shirts? :)

I'd like to see a life so absurdly optimized for productivity that the maximum 10 seconds you save every morning by not having to decide what to wear is worth even mentioning.

The next post will probably be about opening doors more effectively, like Kramer, to save a couple of seconds off the time spent opening doors each day.

Exactly. To interpret that as a "now I have more time to deal with other things" motive fails to acknowledge the fact that Jobs was one of the most prolific critics of subtle details. If he truly had more important things to care about than his wardrobe, he would have worn whatever he had any given day. It may not be fashion, but he established a brand.

You aren't Steve Jobs.

I would give the opposite advice. The easiest thing you can do to make people like you more, trust you more and respect your opinion more is to dress well and appropriately.

Job's outfit and Zuckerberg's hoodies work the same way (whether that was the intention or not, I think not). The same part of human brains that stupidly subconsciously judges people by the way they are dressed is doing the same thing with them. They show status by being able to openly reject the standard social expectations around clothes.

So call it a psychology hack or a life hack or whatever but if you are a founder of a startup then you are meeting and needing to impress a fair number of people. You can handicap yourself because you are convinced that it "shouldn't matter" or "this is the startup uniform" or you can be pragmatic about it and gain an edge for relatively minor effort.
