I have worked in my field for 25+ years. For the first 15 years I worked on the 'front lines' doing the grunt work of the profession. I then moved into management and then into consulting and teaching and that is what I do now. However it has now been 10 years since I was on the front lines and actually doing the work and I have started to feel very self conscious about the fact that I am teaching and advising on work that I myself haven't done in a decade. I know that when I was on the front lines, listening to someone try to tell me how to better do my job who hadn't actually worked it in 10 years would have made my roll my eyes and tune out.
How do people navigate this? I am always on top of recent research and what the profession is doing but I am not actually doing the work - just telling others how to best do it. On one hand I have the time and focus to bring forward recent advances they don't have the time or energy to look into, on the other hand, I no longer feel I really have first hand experience with what they do day to day as a lot has changed in ten years.
How do people stay confident in advising others about a role they no longer do?
