We're all addicted here and the problem is that there isn't a former addict on this site to help pull us out of it. I've been playing for just over a year too and if anything the addiction is getting stronger.
I can help you out. BASED ON PERSONAL EXPERIENCE, here are my easy steps to avoiding Disc Golf addiction:
1. Be a terrible player.
Throw lousy drives. Miss putts you should make. Never get comfortable with a midrange disc. Never get an ace. You get frustrated and before you know it, you haven't played in 6 months.
2. Drive a lousy, piece of crap car that you don't enjoy being in.
I drive a 1990 Honda Accord that has seen its better days. I don't like riding in it, so I don't go out of my way to drive to a Disc Golf course because the experience of being in my clunky car is so brutal.
3. Find a girlfriend who tolerates a lousy, piece of crap car, AND who has NO APPRECIATION FOR ANY ATHLETIC ENDEAVORS WHATSOEVER.
My girlfriend fits the bill. She CLAIMS she would play a round with me, but I know better. She'd get all irritable after about 3 holes. So any Disc Golf time for me is something that would cut into my valuable time with her, gardening and checking out antiques.
4. Get a salaried job where you have to work about 55-60 hours a week just to do adequately and keep your position, leaving you exhausted and praying for early death on a regular basis.
I've had jobs like this in the past that helped me avoid Disc Golf addiction by leaving no time or energy to sling plastic. Now I have one of those jobs that limits itself to a mere 40 hours a week(Sounds like some Euro-Socialist nonsense), and the Disc Golf addiction is creeping back in.
There you go! That's how to do it. And for the record, I've played 12 courses in 10 years, and bought about 40 discs over that time.
