I find that some elements of being frugal are harder, some are easier when working full-time. When I'm at work, I usually use my lunch hour to run errands (consolidating everything into one trip) and planning - meal planning, matching sales to coupons, etc - that for some reason I tend not to get down when I stay home. OTOH, there are lots of time-intensive frugal things - gardening, making my own laundry soap, baking homemade goodies - that I find I don't have the time or energy for on a lot of nights.
