Hedonists, rejoice! A couple of Columbia University researchers have found that in the long run, people tend to regret having missed out on opportunities for pleasure -- and they wish they hadn't been so diligent about working. What's more, our attitudes reverse over time. In the short run, we're proud of our ability to work hard and delay gratification. But years later, we regret that choice.I'm saying though, stay tuned here and find out whats going on and throw caution to the wind so you don't regret it later. You only really regret that hangover while you're experiencing it cause we all know you'll do it again the week after next.
