The easiest way to complete Fabulously Wealthy aspiration?

I do this aspiration quite often, it's my favorite. You can't beat the weekly interest. Free money is always good! I do gardening, painting, and writing to get that money rolling in. Definitely use the flea market tables if you have CL. I also don't like sending my sims to work and prefer to have them work from home by crafting or gardening and have them make money that way.
