How often do you tell yourself that you are wrong, bad, inadequate, unworthy, a jerk, stupid and so on? I've found, in the many years I've been counseling, that most people are frequently inwardly judgmental.

If you don't have people in your life that you regularly feel encouraged, empowered and inspired by, then it's time to "hire up." Seek out friends that will engage, challenge and inspire you on a regular basis.
