I think the biggest difference between successful devs and unsuccessful ones is the hunger for constant learning and improvement. You can lack that hunger if you have a CS degree or not. I've observed this at my company and others I've worked for as an almost constant.
yes, completely agree with this. To be successful, it has to be your hobby and you have to be hungry to know more and improve. It is also required anyway because CS and technologies changes rapidly. For example it is not common to write UI apps in Tcl anymore. :) but it is now more common to use LXC and Docker instead of virtual machines and shared library versioning hedeaches.
