Three basic human fears about what we do:
That what we’re doing doesn’t matter. That, quite probably, it’s meaningless.
That what we’re doing doesn’t help. That it doesn’t make a contribution to anyone.
That when we’re gone, all our efforts will amount to nothing.
Notice how it’s our busyness that has such amazing capacity to distract us from our fears, to numb us to them. And that it’s our busyness, precisely because it distracts us so well, that has such capacity to make our fears turn out to be true.
