Introduction, learning, gathering, total immersion, then thinning. After a person has learned as much as they can about the subject, interest wanes and thinning occurs. At that point a person considers themselves well schooled on that subject and they move on to something else. Do this several times in your life and you become an interesting person. Better yet, do it your whole life and you become a very interesting person.
I owned and used a Winchester for 30+ years and happened upon these sites. With a lot of help and direction, I found out that the Win is probably completely original and very valuable. So I got an NPM as a shooter and that is another direction to go. After reading "War Baby" I have a renewed interest in these weapons and find all of them, mixmasters whatever, very interesting. I would never change any part on any of them unless it broke, which is why I have the NPM as a shooter. They are what they have become and changing them into something else isn't respectful to each weapon. That is important to me.
