We learn more by looking for the answer to a question and not finding it than we do from learning the answer itself. ~Lloyd Alexander
Golly, sometimes when I go to the dictionary to look up a certain word, I end up reading every word around it. Or I might go to the Internet for a specific subject and I end up reading so much more.
I can agree whole-heaertedly. I often find out more about sideline subjects and become interested in those as much as the main subject of any word or phrase I may be searching for. When searching online, this is almost always the case.
