It seems that the “job” of indie dev is becoming quite popular in the net. No wonder, since recently it got coverage from big media like CNN and so on.
The problem is that most people think that being indie dev is easy, while that isn’t really the case.
Some good advices can be found in this Macgames & More webpage.

They’re good and valid not only for Mac developers but in general 😉
In general I’d like to warn anyone that is not easy, so “don’t burn the ship” unless you really can (i.e. you have no family to mantain, etc).
Of course you might think I’m saying this because I don’t want more competition… 🙂 but when you’ll have your first game out and you’ll earn 100$/month maximum with it, don’t complain!!

Being a successful indie takes time (I’d say at least 2-3 years minimum to get a stable income), and even if you ask more famous (and successful) developers like Goodsol or Dexterity, they’ll reply you the same.
