I urge you to go through the 'words of wisdom' thread thoroughly. It will put a lot of things in perspective for you. Also, before you do decide to take the plunge, ensure that you have 3 things

b) Enough funds to take care of basic expenses for 6-8 months
c) Family buy-in (most important in my books)
