[I]f you punish yourself for trying and failing, you stop wanting to try in the first place, as it becomes associated with the negative emotions. Also, accepting and being okay with the occasional failure makes you treat it as a genuine choice where you have agency, not something that you're forced to do against your will.
So maybe we should celebrate failed attempts more often ... I for one can't think of anything I've failed at recently, which is probably a sign that I'm not trying enough new things.
So, what specific things have you failed at recently?
The administrative admin of the group I was working with told me something that started my habit of brushing and flossing: "It's simple. You only have to floss between the teeth you want to keep." This evokes lots of images for me.
That was 15 years ago, and my habit is still strong to this day.
