I also quit smoking many years ago, thank goodness.
I also have no (human) children.
I also pay taxes that would make your head spin (has anyone ever heard of Howard County, MD? Look it up - you'll be amazed) - BUT we have the best schools in the area (at least), there are families from Japan coming to this county to send their kids to school. This translates into retention of higher real estate values, even in a bad economy, and really good county programs. That's another part of the investment - it's generally a better quality of life where your taxes are higher. BEFORE ANYONE LANDS ON ME ABOUT THAT STATEMENT - I said GENERALLY - there are always exceptions.
I also consider these costs an investment.
