Am I spending my neuroplasticity wisely?

I’ve been setting up structured journal entries recently - quick morning notes, weekly and quarterly retrospectives, etc. As part of this I’ve been curating a list of questions to help self-assess how I’m doing at any given time.

Some of these questions are simple bio-maintenance checklist entries: how’s my diet? Am I getting enough sleep? Are my cholesterol and triglyceride levels normal? Have I been getting enough vitamin D? Have I been doing resistance exercise recently? Cardio?

Then come some less concrete questions: have I been keeping myself intellectually engaged? Have I been engaging in some regular form of artistic creation? When’s the last time I did something nontrivial just for the fun of it? Aside from work stuff, when’s the last time I finished a project? Speaking of work, how are things there? Attempts to answer that question could fill multiple blog posts, so for now I’m going to focus on a specific angle pointed out by
