Be sure to ask yourself - is it the type of work you don't like doing or is it the company or manager that you're currently subjecting yourself to?

After spending a few years of my life contracting exclusively at non-software companies, I can definitely say that the culture can vary greatly from shop to shop so far as how well it caters to people who are there to hone their craft vs those who just show up for the paycheck.

Also, don't forget - jobs at software companies can suck too! :-)
