I found myself really liking this section. Unfortunately, I think it was because it helped validate my inner fears that manifest as procrastination.
Overall, I liked the article, but be wary of using those early stages as a excuse on which to continue doing nothing.
On the other hand, I have done a couple of test/soft-launches this year, and have lost my fear of failing on those. That's more than I had done in the prior 10 years of being a programmer with aspirations, so it's progress.
I still struggle with probably doing too much before testing an idea, but I also struggle with doing too little, so I'm trying to find a balance. Learning, still, really.
