I just love how some people get themselves into hot water at work or home over Facebook. It is usually from something that you wrote, that in a momentary lapse of reason you forgot is not private conversation. Well  If you want to paint a positive outlook of yourself, post pictures where you are smiling. According to research from Sonoma State University in California, if you want people to look at you in a positive light, post pictures where you are smiling or in a relaxed pose. This also applies to future employers looking at your Facebook page.  Remember a picture truly says a thousand words.
