Do I really have to pick one mistake? - I accepted an ever increasing span of responsibility without commensurate increase in compensation or real authority (promotions). - I deceived myself into believing that giving up vacations, personal time, education, working through illness, etc was ok because “senior executives” were asking me to do so and I was a “critical team player” in the corporation's success. - I didn't appreciate until too late that as a technical person in a technical role in a non–technical organization I would be evaluated on KPIs/OKRs/PBCs which were important to the non-technical organization but meaningless to technical peers and useless when trying to move on to future roles.
