We have a saying in alanon about finding contentment and even happiness whether the alcoholic is drinking or not. I personally like to apply this to life in general, because I find it so hopeful.

I can find happiness and contentment, regardless of what other people do or don't do. It is mine to find, not someone else's to give.

And having this shift in attitude has gone a long way to helping me become a more pleasant human being to be around. More attractive, too, or so I'm told.
