Daboo congratulations on quitting your job. I am 31, married with 2 children, house in the burbs, and I just quit my job Monday. I told them I was going to a competitor so that they paid me for my last 2 weeks, but truth be told I don't have another job lined up, and I'm not in a hurry to find one. Luckilly my wife makes enough running her own business part time that I don't have to race back to work.
Enjoy your time off. When you're ready to get back to wok you'll have a better idea of what to do. The blog is a great idea, or perhaps you could make house calls to help people with their computers? One of our neighbors did that contracted through our local cable/internet provider. I don't think he worked for any less than $50 an hour. We called him when we had a virus, and my wife was running a different biz on Ebay at the time, so we gladly paid the $50 to keep the business doors open so to speak.
