There are lots of things that I do that do not have an immediate reward. Some of them are recognizable like dieting and exercise. I change my diet, but my waistline does not immediately shrink. If I eat a pint of ice cream, I don't expect to see my weight increase by 5 pounds over night. But over time these things have a very definite effect: though my day to day weight may vary like a drunken sailor navigating an alley, the trend does go up or down.
This posting is about the same principal applied to a different area: the mental or spiritual. There are exercises that I do that have a long-term benefit, but I often times find them even harder to do than the physical ones. After all, you can't measure mood by standing on a scale and then use that info to graph your progress.
One of these exercises are my BYBS postings. Over time I have found that I lead a happier life when I regularly stop and think about the things I am grateful for. As a person who is at times overly focused on stuff that I don't like it is important for me to remember the things that I do like.
If you would care to share, comment on similar examples of mental or spiritual exercises that help you.
