On a personal level: yeah, taking a 3-month sabbatical was a good call. I'm *way* more productive now than I was six months ago.
Currently speed-running ten years of ecosystem evolution for #Querki. (Which had been stuck on #Scala 2.11 / #Play 2.5 for a decade because of Dependency Dumb.) Often frustrating, but so far I keep managing to get past my roadblocks fairly quickly, and it's mostly fairly meditative stuff...
