I may spend money on things that make me happy, but I find nothing that excites me.
Even with travel, I have found that we are good with one long trip each year, alternating between a 2-3 month European trek with a 2-3 month RV trip. Did the Alaska trek this year, so it will be Europe for 2019. Maybe I will revisit Spain, and go see places not crowded with tourists like the Asturias region.
Oops, got carried away. Back to budgeting issues, my travel style is pretty low key, I have never had to budget for it.
Prior to our making the RV trip this year, a cousin of my wife visited, and upon learning about our upcoming long trip, asked what distance we would be driving. When I said it would be more than 10,000 miles at perhaps 8mpg, and gas in the Yukon is up to US$5/gal, she said "Uh, that's something you must make budget for".
I thought to myself, "Of course, travel will cost a few grands no matter what". I only add up the cost afterwards, not during the planning. It's simply because it has always been less than what would really concern me. LBYM means never having to count every thousand dollars.
