It is true that those who choose to be critical of others and their work are often suffering from issues of their own. Sometimes they are deflecting their own disappointment and pain by finding fault with others. Some people simply avoid doing the work of change within ...
So, how can one determine if you are giving feedback or just being critical? First, ask yourself honestly if you fall into any of the examples above or are you just nitpicking for the heck of it? Do you have an agenda regarding the person or the group in question? Do you really believe that passing on this information is necessary? If so, once again, ask yourself why? Will it improve anything down the road or was it just an honest mistake better left alone?
Feedback is about the law of giving and receiving, and it is vital in your creative life, whether you are expressing as a writer, an artist, a parent, a student, a business person, an employee, or a member of a group. It is necessary for your prosperity. If you work at a company, for example, it behooves your employer and co-workers to practice the art of feedback as opposed to criticism. You are also under that obligation. Only by participating in this positive cycle can the uplifting flow continue, which will move everyone involved forward. Criticism, on the other hand, gnaws away at an individual's confidence and the mission of the company until both are traveling on a path of erosion.
