In reply to Blizzard:
My old job made me depressed. It also made me very cynical about politics, but I don't think that would have been much different had I not seen it in detail, first hand.
Rather than affecting my view or perspective, I think my old job gave me insight. Other people in the profession had very different views and perspectives to me.
When I start working again later in the year in my new job, seeing 15 or so patients a day, it might give me a bit of insight into what certain kinds of people are like (but it's not like we're going to be talking about much - the conversation in this line of work generally revolves around the relative merits of lenses 1 and 2).
