I was recently accused by my close friend of sacrificing a long-term dream for some short-term gains. My thought-process and the discussion were a lot more complicated, but yes, I might have made some impulse decisions. Which, according to The Wall Street Journal / adapting a report from the Fortune magazine, was a human-nature:
"Why is it so hard to save for retirement? It may have something to do with how our brains are wired. When researchers at Princeton University's psychology department ran brain tests on undergraduates, they discovered that humans are of two minds, writes Justin Fox in Fortune magazine. The research showed that when it comes to money matters, part of the brain is hard at work making calculations and weighing options. But when participants in the study opted to get their money now, the more primitive limbic system of the brain 'lit up as if it smelled dinner.'"
