In time, I figured out that the problem wasn't our money, but the fact that I experienced big time loss aversion. I didn't want to lose time with our son.
Unfortunately, I didn't see a way around losing time with him because Rob was in school, and I needed to bring home the bacon. But over time, I started thinking about money more creatively. Could we save up enough for a long sabbatical? Could we reduce our expenses more? Could I earn some income without having to get a job?
Almost exactly 18 months ago, Rob and I came up with a plan that would allow me to quit my job by July of last year. We saved up a ton of money, but a few months later, I chickened out. I didn't trust that we could keep our expenses low enough. Then we came up with an alternative plan called the get mama home checklist, and we also decided to have another kid before I quit my job.
So, we marched our way down the list, and now I've officially (almost) achieved my goal. I submitted my letter of resignation to my full-time employer, and after my vacation time runs out in a few weeks. After that, I will be a stay at home mom.
