Time for New Job?

I work as a technical writer for a small company. I make my own hours, have the option to work from home, and love the people I work with. The only problem is that I am bored out of mind. I have little to no work on my plate and am pretty much just going to work to put my time in and not much else. This has been hard on me emotionally: not feeling useful. So my question is, do I try to find a new job potentially out of my field? Or should I grin and bear it because it is such a cushy job? My husband and I are not planning to have children until a few more years down the road.
