This is about problem situations being one's motivation, but could be (incorrectly) used to argue that it's necessary to keep one's problem situation static, since solving anything removes the challenge. Any bad thing at all could be advocated for using a similar line of argument: in a life without endless meetings, for instance, does your leisure time really matter?

In a limited way those arguments are all true: solve something and something else changes in its significance. The question of what to do next, "but after that?" can be bewildering. However, there are all kinds of obstacles that we are ready and interested to have removed. Personally I have no interest in the challenge of being routinely bored to tears, or the challenge of being doomed to die. I'm totally ready for my next thousand years of non-urgency.
