Attending to an important and difficult task head-on is the way to go. The easy thing is to procrastinate, however, things only get worse and more difficult when you do that.
Attending to things head-on requires a concentrated effort to tackle the issue. A half-hearted approach will not cut it. When you break the task down into bite-size actionable activities and concentrate, you will find that the task is not as difficult as you think.
Once done you will feel a sigh of relief and a sense of accomplishment.
