It's not the most kid friendly metaphor but I tend to look at it as "the bucket of fucks". Everything you give a fuck about has a certain amount of weight and there is an nigh infinite amount of things to give a fuck about. But you are a person, you can only carry around so many fucks or else the fuck bucket gets too heavy to move. Having an immovable fuck bucket is dispiriting so you give up.

But the people who are generally successful in resolving the fucks for everyone generally select a couple manageable ones for themselves to handle. But you have to invest DEEP into that fuck. But you know what? Making progress on something is relative. This achievement is HUGE to the people who invested in this particular thing to give a fuck about and it is making things a little better. We can afford to be a little inspired while realizing that all the things in our own fuck buckets are important too.
