A Matter of Disposition?

I read a little saying that one's happiness is related more to their disposition than his or her life circumstances. And I guess that is true. One can be like Pollyanna and look at life through a "cup half full" philosophy. That's not to say, however, that life's disappointments and failures to secure dreams can't throw a person for a real loop. I would have liked to be a career woman, and now at my age, it's essentially too late. I hoped that I might be offered a partnership in the store when one of the owners decided to move on. More recently, I desired to take a mini vacation a scant 12 miles away, when the car overheated and I had to cancel the trip. I find myself in the same circumstances and the usual routine. I suppose one can make some excitement by changing themselves or pursuing a new interest. In my case that might be circuit training or eating healthfully. Sounds as exciting as yesterday's mashed potatoes.
