Why do I ask myself why?
There's nothing wrong with having a sense of accomplishment and saying "I did that!" I've always been that way too. I'm 66, and was a lineman for the Power Company my whole adult life. I can ride by a pole that I worked out 40 years ago, and still feel good about "I did that". I'm the same way with working on my cars, and I still like learning new ways of doing stuff in order to make the end result better. I think the best we can do is keep piddling as long as we're on this side of the grass.....even if it takes us longer to do stuff! :)
