Recent literature has argued that what makes certain activities ranging from curing cancer to running a marathon count as achievements, and what makes achievements intrinsically valuable is, centrally, that they involve great effort.

I propose a revised perfectionist account on which an (...) achievement is an activity that fully exercises or expresses any number of a range of perfectionist capacities. (shrink)
