Exactly. There aren't going to be many times when I care or need to know what someone had for lunch or what tv program they watched. Many people seem to think of FB as a streaming autobiography or as an arena of competition. If you use it that way then it may very well be a negative experience. You will likely come off as vain and petty or you may have a daily blows to your self esteem. It will be like being in high school forever... cool kids and losers
Also I think Kaliope had a good point. This is internal... more of a personal issue than a FB issue. Try to stop judging yourself by other people's standards. Or by your perception of their standards.
