From Motivational Jiu-Jitsu: Staying Positive in the Face of Negativity & Indifference:

I have a simple activity that I do to identify the problem areas, and think about how I can counteract them. Start by drawing a simple diagram: Place yourself at the center of the diagram (you don't have to be an artist, a stick figure is fine). Now, around your picture, draw the people that you deal with regularly: your boss, your clients, your coworkers, your friends and family. Add anyone who provides you with feedback or should be providing you feedback. For example, if your boss is overloaded with her own work and rarely has time for you, put her in the diagram.

The more demanding your job is, the more likely it is that you are having to field negative criticism on a regular basis.

Make sure that one of these "people" is your Inner Critic, since each of us is continually providing ourselves with feedback. You should also add your Work Environment, since a good work environment provides you with positive feedback and an unpleasant work environment provides you with constant negative feedback.

The article goes on to explain how to eliminate negative feedback. I think it's worth a read.
