That was my epiphany yesterday when I canned tomatoes. I loathe running, but I love to listen to runners talk about the experience.
So I thought of how I had prepared for this moment, bought the equipment and set aside the time, and how I just had to take the first step and get started. Then I looked at how much work was in front of me and quailed and wanted to give up. After all, no one was forcing me to do this - I chose to do this because I love it! So I pressed on and found my rhythm and got out of my head and enjoyed my mad skilz. And when I was done, well, wow, the whole world looked sunny and (unlike the runner), I had food for the winter to show for it!
(1 bushel tomatoes: 12 pints pizza sauce, 12 pints salsa, 19 quarts whole canned tomatoes, all pressure canned with help from the children)
Sure, there are other reasons I like preserving, but my reasons are different from my mother's generation and I finally realized that.
