On what subject(s) are you an authority?
Having been retired for just on eight years, I have realised that I am not an authority on anything.
Least ways not anymore. While still working, I might have been an authority on in house processes and product safety standards. But what use is that now. It’s just a rapidly fading memory.
Now I am the very epitome of that age old saying….
Jack of all trades. Master of none.
