All things considered, it has been a mixed bag so far, with the upsides dominating for me, thankfully. As long as I managed to devote some some time and found an opportunity, it was reasonably easy, fun and pretty successful. If, on the other hand, I was pressed for time or (like yesterday!) completely knackered, it would turn into a burden. But honestly, that's exactly what was to be expected. The other thing that is to be expected (but that I hadn't) is that quality is equally dependend on time constraints *and* the state I am in - usually, if I'm not in the mood to take pictures, I don't; now I had to, and it was difficult to even get usable ones in some cases.
Additionally, I sort of expected myself to perform at least decently every day - and found it pretty much impossible. In that respect, I draw my metaphorical hat to all pros - delivering consistently is a lot more demanding than I tought. I'll take it a little easier from now on ...
Anyway, I think it's absolutely worth persevering - so far, I've found out a) a lot about the camera and the best way to shoot with it, b) a lot about nearby subjects and rewarding spots to shoot from, c) quite a bit about my own way of shootings, especially when I'm shooting in less than ideal moments and circumstances.
In short, it's just as much of an education as it is a worthwhile pastime (the latter becoming a lot less so if there isn't any actual time to pass - i.e. to devote to it). I'm going to see this all the way through if at all possible.
