I've cut down (or completely out) a lot of things since an early retirement precipitated by an accident that left me with limited mobility and a sharply reduced income. I established priorities. My closet contained enough clothing to probably last me the remainder of my life, with a few exceptions, so buying clothes is not in my budget.
Eating safe food is a major priority, so I purchase only organics and mostly whole foods. This means I cook from scratch and never go to restaurants. Don't miss that scene at all, and I know what I'm eating. Same goes for feeding my beloved dog: homemade food from organic ingredients. Even with buying organic foods, not buying junk foods or eating out helps me keep my food budget in check. Eating unsafe food ends up costing more long-term with illnesses and healthcare costs. "We are what we eat" has never been more true, especially in the U.S. where the FDA and USDA cannot be counted on to look after consumers' welfare. (Those corrupt agencies are too busy looking after Big Business and Big Pharma.) Because healthcare costs for both my dog and me are priorities, those stay in the budget.
I do not have cable TV (wouldn't watch it anyway), and I use my public library card weekly. I have a Netflix account for $8.55 per month and own a Roku (small one-time cost) that allows me to watch on my TV set. Reading, playing music (CDs I already own and playing my electronic keyboard), writing fiction and articles for HP, corresponding with family and friends and via phone conversations--these are my entertainment. Gas prices don't concern me, for I rarely drive more than ten miles per week.
Regardless of an individual's or family's financial situation, it comes down to what is important for her, him or them: setting priorities and reducing or giving up those things that are not priorities.
Sounds simple, but this does require attention and work!
