Don't Sweat the Small Stuff . . . and It's All Small Stuff. One of the mistakes many of us make is that we feel sorry for ourselves, or for others, thinking that life should be fair, or that someday it will be. It's not and it won't. When we make this mistake we tend to spend a lot of time wallowing and/or complaining about what's wrong with life. "It's not fair," we complain, not realizing that, perhaps, it was never intended to be.
