We all have moments of self-doubt and days where burying our head in the sand or at least under a pillow seems appealing. You aren’t solitary in your reluctance to try new things. You aren’t alone in being your harshest critic. We all have that inner voice that second guesses every brilliant idea we have and puts down even our best hair days.

But learning to flip the negative into a positive will get you far. According to a study from the Harvard T.H. Chan School of Public Health, having an optimistic attitude may help people live longer. Not to mention affirmative thinking can bring you job success and overall high achievements.
