Humor is something that produces laughter, thus it is paradoxical. What you find laughable, I may find offensive. What sorts of events, words, pictures do you find humorous? We know now scientifically what we have known for years - that it is important to focus on things that make us laugh. If we can discover the humor in any event that is happening, then it is like good medicine; something that makes us laugh in such a way to forget what has been hurting us, even if it is for only a moment.
Today, find some humor in your life. Think about what it is that makes you laugh and invite it into your life today. Go rent a movie that you find humorous. Check out the comedy clubs in your geographical locations. Comedy clubs exist for a reason, a very good reason: to make us stop taking ourselves so seriously and enjoy a cognitive interruption that relaxes our synapses.
