I always liked yak shaving, but avoided it because I knew it came with costs and tradeoffs. More recently, with the help of AI, I’ve been doing lots of it, as the costs and tradeoffs have greatly diminished. In fact, I’ve learned that building my own tools and frameworks, when done properly, comes with huge performance benefits and helps me understand the problems I’m trying to solve much more deeply. There has never been a better time for yak shaving!

Personally, I find it difficult to competently reason about a system unless I've built my own version of that system. So if you make a practice of building your own versions of things, you end up with a more robust mental library of how stuff works. For this reason, I've never seen yak shaving as a waste of time. The yak shaving was at least 50% about loading the abstractions into my brain fully.
