18. You never laugh at yourself

“A big mistake is not knowing how to laugh at yourself, and be too easily made uncomfortable or embarrassed if others give you a little good natured ribbing or you make a mistake in front of other people.

People like it when you show you are imperfect and can laugh about it. Also, many people tend to socialize by casually joking around without giving it much thought, and this can include poking a bit of fun as someone there or about something the another person thinks is important. Give people the benefit of the doubt that they don’t mean anything bad by it, just joshing around. If you show you can take it (and better yet that you can dish it out, too) people will like hanging around with you much more.” — zazzlekdazzle

19. Your eye contact is too intense

“Misunderstanding the importance of eye contact and literally staring at me in the eyes for the whole conversation. Eye contact is important but it’s nice to take a break and glance at your surroundings periodically.” — Grateanswer
