Purpose in life. Give yourself hundreds of millions of dollars. What now? Many people might say they'd go retire on a beach, and that's really fun for like a year or two. But even endless self indulgence of that sort becomes quickly pointless.
For all of us stuck in the hamster wheel, purpose is easy - because it's forced upon us. But for those who manage to step outside of the wheel, what now? Taken to extremes you even see things like 90+ year old Warren Buffet deciding to step back in the wheel, continuing to show up to grind his days away at the office.
If you appreciate that lots of behaviors of people are them simply looking for a purpose in life - a lot of things start to make much more sense, running the gamut from political extremism, activism extremism, or people who already have practically infinite wealth just turning life into a game of 'make number go up.'
