We all have a natural desire to be interested in life. There’s nothing wrong with that. Our mind likes stimulation. But at the same time, we also have a tendency to be lazy and impatient. Things that we’re involved with for a long time, like a marriage or a career, may start to lose their thrill after a while, especially if we take them for granted. When our day-to-day life no longer feels new and exciting, sometimes we long for a change, any change, just to shake things up so we can at least remember what it feels like to be alive. That’s why, even if someone has a very good job, or a very good relationship, many otherwise intelligent people go out and do something really stupid, just to liven things up a little.
