I work in a tech field doing Web Development/E-Commerce consulting work and this field is a bit different. Its easier to get your foot in the door with no degree in this field. Buts its always better to have it. That said, half the people I know in this field have degrees in things not at all related to our jobs, myself included.
I say if you want to quit school, do it, its your life. Maybe you'll regret it in the end or maybe not, but college is not for everyone, and sometimes, its not for you until later in life. There is no set formula to life, so just educate yourself as best you can and then make a decision. You can usually alter it later.
