10 years ago, when I started blogging, I coined the term journeyman of some to describe myself.
I explained it as follows:
You've heard the expression "jack of all trades, master of none"? Well, I'm kind of in the middle. I have a number of diverse interests that I've pursued to a level I would say is beyond an apprenticeship but has not yet reached (and will likely never reach) mastery.
I'm not a jack of all trades.
I'm not a master of none.
I'm a journeyman of some.
