The nice thing about being a solidly upper middle class dual-income professional family is the ability to not have to worry about constantly seeking the absolute best returns on everything. Not like we can take it with us, we still have sufficient rainy day funds set aside, and I'd rather spend my time and mental energy elsewhere, so I do. And I understand that's a privilege.
We're fortunate enough to be at a point where we don't have to worry about maximizing everything. If we get a 5% overall return on our savings instead of 6% because I threw money at the mortgage instead of into a CD, oh well. I'm still fortunate enough to have money in savings.
It's not like we're spendthrifts; I drive a 7-year-old Honda CRV and most years our biggest vacation is flying to Vegas on Southwest to visit my parents for Thanksgiving. And we absolutely had our penny-pinching moments for the first decade after law school when we had student loans plus two car loans plus rent and eventually our first mortgage and a baby, all on two state government salaries for baby attorneys which, I assure you, are not the same as what a first year associate in Big Law is making.
If a coupon is in front of me I'll use it, if things are on sale that's great and we may stock up on that to take advantage of the sale, but I'm not driving across town or hitting up three different stores just to save $2 on soda here and $1.50 on butter there.
