I've thought about the same thing, Bambi! In my case I know what got me here... being a forum member and moderator. I have often had to look things up for someone and when I do I learn, too! Just reading what other knowledgeable members have written is a learning experience as well.
I can also do anything now, but I just choose to do somethings over others. I often take patterns or knitting books to bed and read them.
