I agree, finish what you gegan.
I have studied mathematics and informatics and besides I implemented Excel makros for business companies to earn some money.
Afterwards I was working as freelancer (Electronic Data Exchange / EDI).
One year later I applied for a developer job at SAP.
I never missed to have basics of mathematics and software engineering to rely on when designing software.
If you are looking for excellent books on innovation, read books of Tom Kelley (Idea, Palo alto). The basic of innovation are part of 'The Art of Innovation'.
Try to practice on implementation. Maybe you can assist companies to use widgets to speed up simple tasks like 'application for leave' or help them to use wikis to improve collaboration of their employees.
