Since people with obsessive-compulsive personality traits often feel that the right thing is to hold on to money, time, objects and compliments, they may miss out on the benefits of generosity. And since they tend to get engrossed in goals, projects, and fixing things, they may neurologically wire themselves into a narrow focus which excludes generosity. I can’t guarantee you’ll feel happier if you engage in large or small acts of kindness, but I do believe there is a very good chance that you will at least feel like your life has more meaning—and, silver lining for the compulsive—you’ll feel like you have more control over your mood.
