I don't guys. Guess I'm different. I am satisfied, at least with the trains, Yeah, when I go to a train shop, I sure can spend a lot of time dreaming and thinking - but I have some self-control, so I don't spend the same amount of money.
Maybe it helps having a smaller layout, so there's only certain items that I can run, or will look right on the layout. I'm not enamored with all the control technology, so that saves me money: conventional only.
I've read studies that show that children that are not pushed too hard and too soon to read, write, etc. hang on to their creativity and imaginations much longer. Many artistic personalities have backed this up. And this must be the case with me too.
To me, the "Magic of Lionel" is not necessarily technology. It's using your creativity and imagination. And I love seeing how people can take the same exact items I have on my layout (like Plasticville buildings for example), and do something completely different with them.
I've never been a "keeping up with the neighbors" kind of guy. If I was, I wouldn't be in the hobby. I don't care what's on the neighbor's layout, I care about what's on mine. And I like what's on mine.
A hobby should make you happy. If it doesn't make you happy, you don't need a new hobby - you need a change of perspective. Your attitude equals your gratitude.
