Welcome to the forum. Sorry about your personal loss, hope this New Year marks a fresh and great beginning for you.
Since the question more or less positions itself on enterpreneurship, I think I will provide you with a few links for you to read at your pace and to make your own mind up. I agree with all the others who've responded so far (including - you are self-sufficient already ;-]), and as a (budding) entrepreneur myself, who am I to stop you, Eh? ;-)
I'm going to try and balance the viewpoints here by offering pros/cons together
-> British article, and deliberately pessimistic to make you understand the risks truly.
-> Indian article, Yahoo is overhauling its site, so I could not locate the original article (Sorry about it). However, this is a universal post, dealing about WHY being an entrepreneur is good, and an article that is basically Kiyosaki's several chapters from several books, rearranged into a cogent single page article.
-> American articles, so directly applicable. Very optimistic too. ;-)
Here's to a Happy New Year ;-)
