Do you have a favorite productive hobby?

I'm using the word hobby loosely, meaning anything one does for pleasure, even if it technically falls within their job responsibilities. As far as the term productive goes, I'm defining this as something that develops needed skills, produces items needed for living (such as making clothing, or obtaining heating for the home, produces/gathers/acquires food or water, or builds/maintains shelter), produces items or services that bring in income, or elevates the living experience through one's talents. The key is, you derive pleasure from doing any of the above.

So what is your favorite productive hobby?

Can you guess what mine is?

I love to bake. I would bake even if it wasn't part of my job description. 

I began baking when I was 8 years old. My best friend and I went to different schools. But on Saturdays we would get together, and instead of playing Barbies, we'd bake something in her mom's kitchen.

I suppose some of the motivation was that I got to eat some of what I baked. But also, I just enjoyed baking. 

Over time it became something I could do with success, most of the time.

I have other productive hobbies. When my husband and I got married, we talked about how we could spend our free time in ways that brought us closer to our financial goals. I pledged to vegetable garden, sew and repair clothing, bake, and learn to make our spaces more beautiful with little money. 

I don't always love vegetable gardening. Today was just a lot of hard physical work, as I dug compost into another bed. But I reminded myself that not only am I working toward providing more fresh food for my family, but I am keeping myself fit as I grow older. 

Sometimes sewing holes in socks is boring. But it's something I can do that will extend the life of clothing and postpone the purchase of new items. I enjoy making things, using the skills I learned as a girl. I sometimes sew clothing (like pajama pants) for family members as gifts. By buying fabric thoughtfully and carefully arranging the pattern pieces on the fabric, I can make a pair of pajama pants for less than the cost of a new pair of quality ones. 

I know my baking is very productive. I can bake a loaf of really good wholegrain bread for a lot less than buying commercial loaves. And it's just fun to bake. I take a bunch of ingredients, combine them in specific ways according to recipes, and poof, a wonderful baked good results. That's really satisfying.

What productive hobbies do you enjoy, and which one is your favorite? Has anyone here turned a hobby into a side hustle?
