An article that I read recently that addresses the other side of knowing what your success looks like: https://captainawkward.com/2020/05/11/1267-how-do-i-set-goals-if-i-dont-want-anything/
My career goals have always been modest and are pretty much satisfied at my current company (non toxic culture, healthy manangement, robots, making a positive impact), so I'm trying to think more on the lines now of "no regrets about missing an experience while on my deathbed". Recent events have helped wrt focus. :-)
