When I was first learning carpentry, I always stepped up in plateaus regarding skill and speed. First I got a new task to be done Correctly, repeatedly, then I focused on increasing speed. If I went too fast too early, I'd make a wrong cut, for example. Then, I go cut again, maybe use another board, ultimately slower. I always kept that principal with me, first focus on "doing it right, the first time", as they say; then increase speed to the levels of the experienced workers.
I always get a sense of the time that is bid, and aim to fit the work within that. On the other side, a few years ago we were boat building and the context was: "everything should be perfect. The time nor budget is no issue, just make sure it's great." This sounds luxurious, but it also brings a lot of responsibility because there is no excuse if your creations are not up to spec.
Some pruning jobs lately have been within this open context, so I can focus on properly accessing every section of the tree and doing it all clean, to my absolute highest ability. Then, elsewhere if it's a quicker prune, I may use the pole saw to get at the most glaring stuff, covering a wider area quickly. The finish cuts may not be as proper as when I am right there, but,
another maxim from an early mentor: "Better roughly right, than precisely wrong."
Namely, better to prune the entire tree to an equal level in the time allotted, than do a great job on one half and not reach the other side.
This time/craft dynamic can be super challenging. Of course we strive for our highest ability; then there is also a lot of respect for doing a job that meets the basic intention of the client, making them happy with the result, good enough for our own satisfaction, and completing the whole deal in a way where our companies thrive.
It's a great conversation.
