Thanks for the answers. I’m not sure either of those address the question of how to commit to doing it for at least x weeks/months. I think I just need to beemind some number of 45 minute sessions a week, and also decide up front how many weeks/months I think I should give it for a “proper try”, but how to stick to the second part?
I guess the general beeminding question here is “how to not cry uncle too soon”. A one week akrasia horizon here seems too short. Maybe that’s the solution: up the horizon to a month or more for this goal? Don’t know if that’s configurable in beeminder, or whether there’s some other way to approach that.
It would be nice to think up some other ideas to stick to what I decide about how many weeks to try it for, I’ll think about that…
Re swimming: I reckon a proper try is going to be a few months rather than a few weeks. Maybe exactly how long is is more a question for swimmers than beeminders but I’d love to hear opinions from any swimmers here. As for how many times a week, maybe I’ll start at one a week and work up to three. Turns out my local swimming pool is helping me here: if you sign up for a course they insist on you paying for 2 months of swimming, and the course is no extra cost on top of that (this is better.org.uk, a non profit co-operative that runs government-built pools etc. here in the UK).
