I always said the way to have a happy life is to be easily amused and have a short memory! I try to focus on the positive things in people to outshine their faults. Also it is good to remember that the things we don't like in others are the things we don't like in ourselves, it is the reflection that hurts. When I had a NDE these demons danced before me in a terrifying way but them moment I realized they were pieces of myself, they melted away into much less terrifying forms and I moved on to the next part.
