Risk/reward

In personal affairs, or the market of money,
Its chemistry that makes, days cloudy or sunny,
from ten million years, of evolution it’s clear,
we’ve evolved a psychology, that can be driven by fear.

But more common than fear, in the market or love,
It’s the goal-directed behaviors, that enable the dove,
Be it romantic love, or that big market score,
It’s that molecule, dopamine, that motivates us more.

It’s a dopamine gate, that lets blood flow to the brain,
that neurotransmitter so small, gives us such pleasure or pain,
when levels are low, we’re cautious, lethargic, like a slug,
but when levels are high, we’re adventurous, then smug.

Though our psychology is understood, a little bit more,
Seems we’re still, as a people, rationally poor,
Yes, irrational, we are, in a predictable way,
So our fondness for risk, is here to stay.
