Irrationality

Trauma. Or great great urgency can create the need to self medicate.

Humans require basic things like food and shelter and perhaps a hierarchical purpose. Missing one of these things can cause great stress. In modern society, you can find food and shelter even with no money, but unaddressed trauma or continued rejection from the hierarchy can create a need to self medicate.

Wanting to be exceptional. To completely bypass the hierarchy can create focus and superhuman, daresay irrational, motivation. This also can be very stressful and require self medication to sustain. It goes against our nature to take on inordinate risk or postpone leisure when there already is an abundance of comfort.

Pursuit of being The Best is crazy and disproportionately benefits the conveyors and supporters at the tragic expense of the risk taker.
