> Identifying that habit as part of who you are is key to it being sticky.
This has always been key to me. I've succeeded to identify myself as a runner, as someone who speaks French, as someone who reads books. But my identification as someone who has meaningful programming side-project, who has a garden and so on is to weak to succeed.
In the same vein, at Volvo's factory outside of Gothenburg they have the obligatory museum. It's just that they don't showcase old, famous models. The museum is entirely built around car safety and how Volvo has worked with it. It is interesting with a company that has been so dedicated to their core values for such a long time.
The way this is told in elementary school in Sweden (source is Swedish) is that the Vasa was too narrrow, given it's height. So then the question is, how much wider should she've been to carry the extra height. Vasa's sister ship, Äpplet (the Apple) had a similar deck layout and was about a meter wider. As a layman, considering the technology at the time, it does not sound so much more wider.
