I'll get a new job, start dating someone, move into different housing, join a new group or activity of some sort, and at the beginning, everything is good. But by the time I reach six months or so, I'm over it. It's stale. It's boring. It's a burden. I don't want to do it anymore. I feel trapped. I'm restless and looking for something else. I'll spend the next year or so in a rut until the next thing comes along. I've been like this for years and I'm afraid it's never going to change. Is there any way to have long-term, sustained contentment?
