It was very disappointing reading how the author found credible podcasts, books and people to follow, only to recommend nothing and leave the reader wondering about this mysterious information.
Author here - Sorry about that. Since I haven't been much of a success, I didn't think people would be interested in my recommendations. But here are a few that I found really helpful:
Books:
The Four Hour Work Week by Tim Ferris,
The E-myth by Michael Gerber,
Running Lean by Ash Maurya
As the other posted said, any resources provided by MicroConf are also great. Basically look up their videos on YouTube and follow all of their speakers on Twitter or subscribe to their newsletters.
If you find a speaker on microconf interesting, follow their talks on other channels.
Newsletters I find useful:
