I tend to agree with the other comment below by sp about value in project results (at least that's my reading) over simply a money-for-time exchange. But after a decade and a half in the industry, my personal experience has been that trading hours for cash has been far less stressful, and more lucrative for me, and I've even been more appreciated, than the salaried work I did for so long. Perhaps it goes something like this: Simple hourly wage work / unskilled or apprentice-type work --> Salaried skilled work --> hourly skilled work as consulting services --> project-based (results-oriented) skilled work as described below.
