Published a free YouTube course with a Google sign-up form to test demand for an 'official' course

By the end of the year, I had decided not to renew my contract at my then employer. I wanted to give the 'solopreneur' lifestyle a proper shot, however it might look. I would continue to work with my previous employer on a consulting basis, but I was actively exploring independent consulting.

But I also wanted to see if building a course had any runway. I published a free introductory course on YouTube to test demand. My goal was to get 25 pre-sign-ups to give me the impetus to build an official paid-for course.
