I have a lifelong philosophy of getting to about the 80th percentile of proficiency of any given activity, craft, sport, etc. A lot of the enjoyment I get from new things is in the rapid rate of improvement while learning and developing. After about the 80th percentile, diminishing returns kind of curse the activity, which is meant to provide leisure, pleasure, and well being. When it becomes a curse, those attributes are diminished. Also, to be in the 80th percentile, you could probably 'hang' with any range of folks involved in the thing, and if I ever want to get back into it after a break, it'll come back. Anyways, B- is quite satisfactory.
