The two actually are intimately connected. The healthier I am, the more work I get done. I've not been able to do solid blocks of work, but by doing it in short (five minutes at a time) bits I'm managing to get Programming Fundamentals written. (It's one of the Netizen training manuals.)
I enjoy my work. I enjoy achievement. I enjoy appreciation. It distresses me when I can't do it.
I've avoided saying anything about the certification. But I will say this:
I'm flattered and pleased that the people who know what I do, consider me a Journeyer. Those people also know how much (or rather how little) I actually accomplish, and certify me as Journeyer despite that. It is extremely good for me to be rated that - it somehow gets it into my head that I can limit my activity to what I can safely accomplish, and still do something worthwhile for someone.
So there. Certification can be good for your health.
