Congratulations
It may feel a tad boring at times but I assure you , you are being rewarded for industry.
Im sure your "know how" and not any sales pressure tactics has led to this and its great to know you can actually pay the bills doing something that comes to you naturally!
In my job ( and Im sure many others) you also get to talk about the same things fairly repetitively but Im aware that many of the folk I speak to actually say it makes a difference
to them after the discussion. That keeps one going
Even if you only take a few quality photos 2-3 times a month , you can keep in practice, and show your clients you practice what you preach

If your Store retails camcorders ect you could develop an interest in that to keep from getting "bored"

Otherwise 2008 is here and something more challenging will hopefully turn up
Well done
