Welcome to the forums.
I don't do the addict route exactly, but I tend to get very involved, very fast, in anything I set myself at. Whether or not that's something I actually want to be a part of... Or not. Normal rules just don't seem to apply. I think (looking back), that it's just me kicking into survival-mode. There's no real thought of the future, or what XYZ will mean long term. I want it now. I make it happen. And... Whoops... How the hell did I end up doing this, again? :confused: Right. I wanted A. Made A happen. That lead to B. Which led to CDEFGHIJKLMNOPQRStoooooop! Dammit. Look. Look before you effing leap. Really. It all made sense at the time. It's only in retrospect it all looks kinda sorta insane.
The biggest trick I have to avoid ^^^ that business? Is to wait. The more excited I am about something, the more I just need to shut my mouth, sit on my hands, and not do (or offer to do) whatever it is I want to. For now. If I still want to in a week / month / year? Sure. Go for it. In a sane(r) & (more) rational fashion.
Flying by the seat of my pants just simply works for me... When I don't give a rip about the consequences. I want what I want, when I want it, let's do this. Caring about those consequences? Has led to a whole lot of temperance. Not all the time, by any means, and -quite frankly- I suck at following the rules. Things other people find easy I find incredibly difficult. ((But why??? But why do it that way? That ways schtoooooooopid... Aaaaargh. I effing hate that way!)) So it's very much a work in progress. But, to date, it's the only way that doesn't have me collecting wreckage in my wake like a dang hurricane.
