Perhaps like many others, you “fell into” your job years ago, and simply stuck with it. Because, well, you didn’t mind the work, had no better ideas or qualifications, or perhaps it was the family business. It has ups and downs, but you reason that you have no reason to complain; you are reasonably content. Some people might regard this reasonable happiness to be as good as it gets. Freud aimed lower; he urged his patients to accept ordinary unhappiness.
So perhaps we should average out our happiness over time, and optimise that? Actually, happiness research looks at both how often you have had happy feelings in recent weeks, and asks about your average – or general happiness with your life. They are related, but they are not necessarily the same thing. Which measurement makes more sense to you? Which have you been using to rate your life? Do you ever think about this to guide your decisions? Are you happy about that?
