Progress Report - September 2018


I post a progress report showing what I did and how my products performed each month. Last month’s report can be seen here.

What did I do

Productive Hours in September

I worked 59 productive hours last month. I watched Money Heist and Attack on Titan Season 3.

I finished the second and started with the third chapter of my book Learn EOS Development. I didn’t write as much as I would have liked as I was at the EOS Hackathon in London. But it was totally worth it. The hackathon was the best I’ve ever been to, from the location (Science Museum), the EOS community, the free food, to the expensive swag (patagonia jacket + backpack). While we didn’t end up in the top 10, it was a lot of fun coming up with the project, coding it, and pitching it to the judges with the team in 24 hours.

  2. Templates
  3. Iterators & Lambda Expressions


My twitter followers increased by 10 to 328.

Learn EOS Development Subscribers

I currently have 144 email subscribers for my book. That’s +36 in a month. I’m curious what my conversion rate will be.

What’s next

Full focus on the next chapters of the book.

  • Write tutorials for free and link to my book. Collect email addresses. All while actually writing the book.
