Finances, How can I get financially set or rich?

I am 29 years old with a AAS degree in health services mgmt also a registered medical istant , I am a single parent and I need a better game plan for me and my daughter. Basically i need to know what can I do to make more money or get finacilally set to the point that I dont have to struggle as a single parent. Whats my best alternative going back to school, starting my own buisness, or investing into something ... if so how do i get started.
