I love the reference to this because I'm working on a side project and treating it as "something I definitely want to ship" and have found that I have higher tolerance for code that I just copy/paste and slapdash together. I've worked on lots of side projects in the past where I was more deliberate about every line of code and learned that shipping is more important to me now than learning something new.
I will say most of the choices I'm making with respect to when to go "deep" with good design are very much calculated. I'm designing the architecture with a lot of thought, but when it comes to laying out UI elements, I will copy-paste and not refactor even if there's a good opportunity for it. It's just plumbing to me, so if it's ugly, it's not a big deal.
