a small goal instead of a hobby

I struggle to say "I do X as a hobby" because it feels...too big? Or like if I don't do it enough or at a certain level, I am faking?? I am instead a goal person. One of my goals this year was "grow one really big tomato starting from a seed," instead of "be a gardener." Maybe it sticks maybe it doesn't. Who cares! It means you end up trying a bunch of low stakes things. Also, a delight to accomplish your goal!
