My cousin just started a company and from the looks of it she's off to a good start.  This makes me wonder what it would be like to go 'solo'.  (Sorry, bad pun.)  Honestly, I'm not even near wanting to move on from where I am.  I have a great company enviroment and I still want my Masters degree before I do anything silly like start my own company.

The only problem is that my family isn't getting younger.  We have kids and a mortgage and all the things that come with a perfect life.  So, when does one make the jump?  What are the tipping factors in a calculated risk to set out on a business adventure?  I'm curious what others feel about new businesses, especially in this 'interesting' economy.
