J = (C^K)/B where:
J is the joy found in com­plet­ing a long and har­row­ing task,
C is the cel­e­bra­tion one gets to par­take in upon com­ple­tion of the task,
K is the knowl­edge acquired while suc­cess­fully com­plet­ing the task, and
B is the bull­shit one is required to wade through to com­plete the task.
Discuss.
