As I always tell my wife, my time is worthless 😁 you are correct though, it did take time but I look at it more as I'm paying myself, rather than paying the oil company or electric company.

I've been burning red oak, it breaks down to about 178 gallons of heating fuel per cord. I can buck, split and stack a cord in ~2 hours. At $4.62/gallon, I'm 'paying' myself ~$420/hour (lest the fuel/consumables for the saw and splitter), significantly more than I make at my day job.
