I get it. But I also get the converse view.
My time is precious and scarce. I'm always balancing priorities. When I give up something to be able to accomplish something else I definitely feel the sensation of frustration when things are not as productive as I might hope.
My dad and I process our
firewood together. I work full time. He is retired. In term time having a half day free to "work" is rare. We schedule things in advance and I want to get a brisk start and make good progress. It usually goes smoothly, but I got really frustrated recently after a 6 hour day when I'd got maybe an hour total with the saw running.
We had run out of fuel. Dad normally handles that, but hadn't realised. He had double booked himself in the morning, and had an hour when he couldn't come out with me. But that cost more like two hours, because there wasn't
enough time before hand to get outdoors and get started properly. Then just after we got going, my mother tracked us down with a list of jobs that need my dad, none of which we had planned for, and that could have been down another day when I wasn't there. I looked at the pile of cut and split firewood at the end of the day with a sense of disappointment rather than satisfaction.
I don't use the big saw alone, and the petrol splitter needs two to operate.
