Currently, for me the challenge has gone from can I build it, to can I build this and everything else I need, and structure it to be maintainable for the long term, so I can keep stacking bricks. This has found me leaning harder into IaC, use of and contribution to open source (for secure ownership, longevity of system and cost reduction) and structuring the development tooling around agents. That will be an ongoing process, but I feel that I'm at the point where I can move onto building what matters. I've already built a few of the tools I've dreamed of having for years (there's a couple of rough edges but it beats the tools I had before), and I think, like the author this will free me up to stay on the next step (building what matters) for good.
