Publishing ebooks

Wondering if I should publish some ebooks to get another stream of revenue going

The theory being if I could get additional streams of income going maybe I could forstall the disaster looming of not having a job. I know that I cannot live here on what I will receive from unemployment. The math just doesn't work. By working as a temp I increase my income and also increase the length of time my unemployment benefits will last.

Free Lance Writing is another Option to consider. Perhaps bedtime reading should be all those books on that topic I aquired over the years.

First I will add to the EBay store to help clear the office and make some cash.

Update: The store is now closed but I do sell on eBay from time to time
