I would simply say a passionate desire to learn everything about their chosen hobby. I have been keeping fish for 27 years (koi for 7-8yrs). I have done saltwater reef, discus, pirranah, ranchu's..so many different type's of fishkeeping. I never get bored of it..I study different subjects constantly. All that reading, and it never feels like work. The hobby simply feels like an integrated part of my life..I think I'd be lost without it. I hope that makes me a good hobbyist.
