Just my .02, but I wouldn’t pursue any additional education unless you have a clear objective.
If you are interested in the business end of new product development, an MBA may be useful, especially if you are interested in M&As or directing business strategy.
Same can be said with any additional education, MFA, whatever. Don’t do it just to do it. Unless of course you like it as a hobby. I know a couple of folks like that.
As for the license, I can’t say, but if it is low-hanging fruit for a better ROI than the other education, it makes more sense to me.
With so many new avenues for funding, have you thought about any entrepreneurial opportunities while doing your day job? Nothing like being in control to make you happy.
