The one thing I have learned is that you can’t think your way through life. The only way to figure out what to do is to do — something. - Meg Jay

Neuroticism, or the tendency to be anxious, stressed, critical, and moody, is far more predictive of relationship unhappiness and dissolution than is personality dissimilarity. While personality similarity can help the years run smoothly, any two people will be different in some way or another. How a person responds to these differences can be more important than the differences themselves. To a person who runs high in Neuroticism, differences are seen in a negative light. Anxiety and judgments about these differences then lead to criticism and contempt, two leading relationship killers.

How do you get the happy ending? John Irving ought to know. One of my favorite authors, Irving writes these multigenerational epics of fiction that somehow work out in the end. How does he do it? He says, 'I always begin with the last sentence ; then I work my way backwards, through the plot, to where the story should begin.' That sounds like a lot of work, especially compared to the fantasy that great writers sit down and just go where the story takes them. Irving lets us know that good stories and happy endings are more intentional than that.

Most 20 something's can't write the last sentence of their lives. But when pressed, they usually can identify things they want in their 30s or 40s or 60s -or things they don't want- and work backward from there. This is how you have your own multigenerational epic with a happy ending. This is how you live your life in real time.

The post-twentysomething brain is still plastic, of course, but the opportunity is that never again in our lifetime will the brain offer up countless new connections and see what we make of them. Never again will we be so quick to learn new things. Never again will it be so easy to become the people we hope to be. So whatever it is we want to change about ourselves, our twenties are the easiest time to change it.
