There's something about getting worked up that feels good. The energy that builds up inside us is amazing, and it can be released in all sorts of ways. One of those ways is through physical action. Sometimes all we need is a good old-fashioned punching bag to release all that built up anger and frustration. Of course, there are other ways to get out those feelings as well. Sometimes all we need is some constructive criticism. It can help us to improve our work, or it can make us aware of things we may have been overlooking.
