I'm full time with internet related ventures. Over the last 8 years I have done/acquired affiliate marketing for gambling, pharmacy and financial products - done
seo services, software development, and web hosting.
Leaving a six figure IT job to do this was a risk but well worth it. I work harder now but certainly enjoy working for me rather than someone else.
IMHO - if you are doing this part-time and make enough to support yourself, take the chance and do it full-time - it's a challenge but the lifestyle and potential rewards are well worth it.
