Now see what you did! I was gonna stay outta this one and let Sabot's fine sentiments stay out there as the mantra we should all remember in model building.
That AMS period for me was a really long time ago - over a decade. I think I have grown as a modeler - and those who don't burn themselves out chasing that last shadow of superdetail on a model project will grow too. You come full-circle again if you keep the right perspective.
The efforts and strides I make on a model aren't to impress anyone, aren't to goad myself on to further, faster, farther, and aren't to win Best of Show at every contest put on by Mankind. The efforts & things I choose to do to a model are done because they're FUN for me - and isn't that where we all started?
Nothing I do is stressful, taxing, frustrating, nor have I ever slammed a kit against the wall because it wasn't working out right. I am guilty of treating all of them like babies, and however long it takes, I'll finish them. That might be a hair short of obsession, but it never causes me a stressful episode.
The toughest thing I had to learn that enabled me to overcome AMS is to learn to build out-of-the-box again. I can do it, but it is really hard. My problem is that I love model building so much - it's easy to slip into AMS. I pass on more contests than I ever would have 10 years ago - the ratio is something like 10:1 right now. I'm proud of that too. And, most importantly, I've reached a stage where it is more fun to participate in a forum like this - than to seek out personal gratification at a model contest.
Now THAT'S when you know you've come full-circle and kicked AMS.
