What are ways to make money you don't have to work in the sims 4 game?

In Seasons, you can have your sim get a job with the Gardening Career, but never have to go into work. When the sim works at home, there is only one maybe two things they have to get done in before the next working day. They can even complete those away from home. Once my sim was asked to harvest one thing. She went outside, found a wild plant and harvest it, and went back to what she was doing before and the job was done.

But to earn money, and not work there are a ton of things they can do; besides what AlanSims mentioned there is also painting. They can also go out side and fish, collect rocks, gems, fossils, plants, frogs and sell those off for money as well.
