If money up front is not an issue you want a university degree. Even if considered as nothing more than a meaningless credential, university degrees pay off over time. More now than ever.
But it needn't be a mere piece of paper. If your classes are teaching you things you already know take different classes.
When you've studied physics up to field theory, biology through physiology and genetics, know how to build an amplifier from a tableful of chips, understand enough statistics to meaningfully criticize a published article in sociology or epidemiology, know how to use Photoshop to duplicate your favorite fancy website from scratch, understand music theory, have a grasp of linguistics and know some basic accounting come back and ask us what to do next. :)
