I've been working on a software product for months and months and months. Today, I installed it on my PC at home. It was strange, it was like I had never used the program before. It was as if the program I had been writing at work and the program I had just installed were worlds apart.
My experience was different, like watching a movie in the theatre vs. watching it at home. When I began using the program, I realized, "hey, this program is pretty fun to use, look at all the neat stuff I can do."
I searched the web for some data to load into the program and found polygon data representing all the aquafers in the state of Maine. "Sweet! I wondered where all those aquafers were." It was pretty cool.
