@AgentQ9A yes self doubt definitely sucks.

I don't think 54 is necessarily too old to change direction - not everyone retires at 65 these days.

I never had the career you made for yourself - I admire you for doing that. I actually do work in a grocery store - but I enjoy lots of things about my job and it suits me fine. It wouldn't be right for everyone though.

What draws you to grocery store work? Is it the lower responsibility/stress?
