I've been "sanding" my personal website ( https://dustinbrett.com ) for nearly 4 years now, and it feels like it could go on forever. Luckily I enjoy working on it.
This is cool and very polished, but my advice (which may not resonate with you) is that you should channel this attitude into some user-facing app instead of letting it basically go to waste on a personal website most people won't see or won't use for more than a second or two.
Makes no sense right? Weirdos, all of them!
