If you’re unconvinced that it’s worth your time to write a career narrative, you certainly don’t have to write one. Most folks get away with not writing one for their entire career and have deeply fulfilling careers despite the absence. That said, if you don’t, then there is probably no one guiding your career. Chasing the next promotion is at best a marker on a mass-produced treasure map, with every shovel and metal detector re-covering the same patch. Don’t go there. Go somewhere that’s disproportionately valuable to you because of who you are and what you want.
