Regret: to feel sad, repentant, or disappointed over (something that has happened or been done, especially a loss or missed opportunity).
On this blog I write often (ok, all the time!) about how much I regret my financial (mis)management and its resulting debt. Boy o boy do I regret it. And the feeling is constant. I can hear your eyes rolling. “Is she going on about this, again?!” Yes. Yes, I am, but hear me out.
