I consider myself a lifelong learner.
Guilty as charged.
Proud of it!
I suspect it had a lot to do with my parent's insistence on reading. From a very early age my mother took my brother and I to the library in the next town every two weeks to get the allotted maximum of 15 books. I would usually devour those in a day or two and reread them till the two weeks rolled around and we could go get some more. My father was also a great reader. Self-employed, he would pull out a good book or magazine or newspaper after supper and read for several hours before bedtime.
In my current calling as a church development consultant, I'm always reading a book (actually 3-5 at a time, but that's another post), conducting research on the Web, talking with church leaders around the country, and oftentimes, just being plain curious about something.
