I've raised chickens for 44 years (minus a few years break for moving to coyote county where I was scared to have them). Milked goats for 30 years until my hands hurt and even with a new machine, one goat was too much milk for us. Quilted for 35 years until making a business of it burned me out. Trained 3,000 dogs in my five-night-a-week classes until "there's one in every class" type of people wore me out.
For me, the only time a hobby overwhelms me is when I've let it get too big (or made a business out of it!) I felt overwhelmed when I let things escalate to having 200 chickens and 40 goats! But I learned my lesson and trimmed to a dozen chickens and 2-4 does with their yearly kids. Too many chickens, too many goats, too many customer's quilts waiting to be quilted can ruin the entire pleasure and just cause stress and guilt.
I'm glad I learned this so I could protect the final passion of my life. I've played harp for 16 years, having taken it up at 50. I don't charge when I play at parties and church and community events (except for weddings). I never advertise or worry about supporting a harp career, and I only accept whatever gigs sound fun. It's a passion that will last because I've protected it against burnout. I'll play every day until they pry my fingers off the strings!
As for chickens, watching my little flock of 13 free ranging in the tall grass, and spending 5 easy and pleasant minutes a day keeping their fresh white coop dry, fly-free, manure-free, and as clean as my kitchen isn't work. I will enjoy them until I'm too old to toss them scratch!
