Thank you so much, Ed!

Well, I did the following to sell my ebook:

1. Validated the ebook topic

2. Repurposed my old blog post into an extensive guide

3. Uploaded it on Gumroad

4. Promote the ebook in my Medium content, Quora and my site

5. Soon, I'll start promoting the ebook in the emails.

I hope this list answers some of your questions. :)
