I have a beeminder goal called “allgreen”. The idea is that on days where every goal other than allgreen is in the green (“outperforming the yellow brick road”), I get to record a point. The goal is set to 1.5 days / week (I’m considering putting it up to two, but so far 1.5 seems good).
It’s been running for a few weeks now and so far I’d describe it as an unqualified success. It results in a much more relaxing beeminder experience where I’m still getting stuff done but it feels less panic driven, and encourages me to look much further ahead with my goals. It also sometimes encourages me to put more than minimum effort in because it means I can plan on getting a second all green day the next day.
Don’t know how it will go long-term - for some unknown reason meta beeminding goals for me have historically started well and gone downhill over time - but in the meantime I’m enjoying the change and would recommend trying it out yourself.
