David--
I don't know anything about you or your practice, but I enjoy your posts.
Based on what I read from you, it is inconceivable to me that you would find Wal-mart greeting to be less frustrating than medicine!
I have reached the point in my life when I ask daily whether I wouldn't rather be doing something else -- my old fallback was "pumping gas in Albuquerque", but that isn't an option any more, with the advent of self-service gas stations. (We don't have self-service in Oregon, probably the only state that has neither self service gas nor sales tax!).
Anyway, the answer is always "no" -- medicine (at least a small private family practice) is a fine use of a life, and its frustrations pale compared to all other possibilities. Amazing Charts has given me something of a new lease on life -- one more tool I have to control my own environment. Kudos, and megathanks to the AC team.
I also appreciate the "beta" releases, and all the comment on the boards to know how to use them effectively. Before I got locked into Windows by medical software, I was a committed user of Linux -- it is the same situation, and really, it is exciting to see the product grow and mature. Sort of like raising kids. Frustrating one day, near tragic sometimes. At the end of the day, altogether rewarding.
