Hi, Sweetie! :waving:
You don't have a "craft disorder"! Face it....you're an artist! Shocking, right?
For many years I've done exactly the same thing you describe - I'd pick up something, like quilting, learn it and practice until I could get 19 stitches to the inch (Masterpiece level), do some projects and then go on to the next artistic endeavor to catch my eye. I'd learn and practice that until I could do it like a professional, and then learn something else.
And all my enthusiasm would be centered in that creative endeavor. And no matter what other less-enthusiastic souls may tell you there's nothing wrong with enthusiasm. It's how most of the world's best things are created - someone has a vision or learns a new skill and his or her passion generates the creation of something wonderful!!!!!
And over the years as I've pursued various art forms professionally I've been very grateful that I had so many learned skills to draw from. Even Christmas and birthday gifts have been much sought after by friends and family and always looked forward to - one year they all got quilts, one year framed pen and ink drawings, one year afghans, etc. etc. etc.
So you go girl! Learn all you can and learn it until you're expert at it. You and those around you will only benefit from it!
