Great video by Colin & Samir analyzing maker Tuber Simone Giertz. Giertz is famous for videos of useless inventions.
I highly recommend this video. There are many insights here for all creators.
► Is your video a product or presentation?
Are you recording just to make a YouTube video or are you filming something that would happen anyway?
► Do you have content-product fit?
Are you selling something that naturally fits in with the content you create?
► What is your definition of success?
Are you doing the work you want to do?
