Build something without blowing up your life

Don't burn the boats.
Build another boat.

I teach entrepreneurship for a living and run four ventures on the side. This is the playbook for building a real side business while you keep the job, the classes, and the rest of your life intact.

I teach this because I'm doing it, not because I read about it.

I'm an entrepreneurship lecturer at the University of Arizona's McGuire Center for Entrepreneurship, and a serial entrepreneur running several ventures at once — on purpose, not by accident.

Right now that means an advisory role with a behavioral health clinic, a curriculum brand built on that clinic's clinical work, a publishing catalog, and a growing short-term rental portfolio. None of it required leaving the last thing behind to start the next one. That's the whole premise here: build another boat before you burn the one you're standing on.
