I make a youtube video every day as part of a do-a-thing-for-100-days project. I've learned a lot from it but one of the key takeaways was that I have much, much more creative energy than I thought (I was really worried I would run out of stories to tell at day 20 or something). The 12 points the author listed seemed accurate but they never really reached a meaningful conclusion. My advice for anyone considering undertaking a creative project: just do it.
