The Bend in the Tunnel

In the past 10 days I have applied to approximately 30 jobs, had 1 in-person interview, and 1 phone interview (different jobs), launched a new book, and had a few magazine publication rejections. I know no more about my future today than I did 11 days ago. I often wonder if there really is a light at the end of the tunnel? Or should I just stop searching for it, sit down, set up camp here, and learn to be happy at this familiar bend in the tunnel? Is there a point in pushing on?
