Every year both laziness and improvements in my frugal mindset lead to gradual habit adjustments. Last year grocery shopping was one the few remaining places through which DH and I achieved our shopping 'high'. Being part hippie and foodie, we'd not only visit the neighborhood Giant but make the trek out to the area Whole Foods, Trader Joe's, and Wegmans at least once a week, each. It was also an easy way to get out of the house with our night-owl toddler after the sun had set, especially when the weather was bad.
After keeping that up for a while it eventually started to get really tiresome. Fortunately our neighborhood Giant has expanded their hippie/foodie offerings in recent years, allowing us to downsize those very unfrugal driving habits.
Another example is that DH used to like making the drive out to a specific Farmers Market in the region because it's the only place our favorite local beef producer sells his product. But as it is a far drive, there's only a window of a few hours on Saturday morning to do it, and lately he's been feeling as lazy as I have about driving, we've simply gone without beef for over a year now.
A while back we started hauling kiddo to the library every week to get outta the house. While a worthwhile time killer, it did start to feel terribly far after keeping that up for several weeks. Nowadays a trip to the libary is also down to just a once a month or two.
Travel farther afield has also fallen into our widening category of so-not-worth it. We attempted a few overnight trips last year, concluding all of them feeling worn out and ready to take a break from big travel for most of this year.
While we strive to keep our very active pre-schooler engaged in the world around her, we've also reached the point of insisting on relaxing and making do at home and the neighborhood within walking distance more often.
This I think is where laziness can compliment frugal living goals.
