That does, of course, assume you are the sort of person who needs a lot of stimulation in life. There used to be a management model that referred to the "T-shaped person." That meant that you can have a lot of breadth, while still having depth in one area. The concept is that the legs of the T vary from person to person and you need to balance those to have an effective staff. I suspect that model is not taught any more, as I've had to explain that to people I've mentioned it to. At any rate, I still find it a useful way of thinking about career planning. I have a broad top bar to my T.
In this case, I hadn't really been seriously looking yet. I had a phone conversation, however, which ended with a "by the way, would you consider coming to work for me" question and a few follow-up conversations with other people. Then there was the whole corporate process stuff, of course, so it all took a while.
I thought I had gotten a lot of the logistics moving before I went on vacation, but came back to find that it was going to take a while to get some things. Like the computer still isn't delivered (I am using a loaner laptop which took a few days in and of itself). It took until yesterday to have a phone line. But slowly slowly things are becoming functional. I do have a couple of more accounts that need to get set up. And some time in January, I need to do a "grip and grin" type trip to meet some more of the customer folks.
I'm also starting to do actual work.
I think this will be a good move in the long run, but the initial phases are always a challenge.
