I'm sorry to hear you lost your job.
<pragmatic>Be sure to put in for unemployment. There is no disgrace in it, especially in this economy, and it may help keep the bills paid for a while.</pragmatic>
I still think you could make a killing with a greek store in Boston. It's a niche that has long gone unfilled. Off the top of my head, MIT, BU, and Harvard all have greek systems (MIT has a chapter of Sigma Kappa) and I'm sure that would get you started. Of course, starting a business is far from easy. It has to be what you want to do and what you really love.
Take care.
