If you like the post, I recommend you to read Start Small, Stay Small: A Developer's Guide to Launching a Startup[1] by Rob Walling.

> "Start Small, Stay Small also focuses on the single most important element of a startup that most developers avoid: marketing. There are many great resources for learning how to write code, organize source control, or connect to a database. This book does not cover the technical aspects developers already know or can learn elsewhere. It focuses on finding your idea, testing it before you build, and getting it into the hands of your customers."

I think your parent was making a joke. But I thought the conference was worth it. That said, one of the two conference organizers has a book that is in the same vein. At the very least, read his book:

Start Small, Stay Small: A Developer's Guide to Launching a Startup https://www.amazon.com/Start-Small-Stay-Developers-Launching...

I think you should read/watch the following 2 resources if you can:

    'Start Small, Stay Small A Developer’s Guide to Launching a Startup' [0]     'Creating and selling a digital product' [1]  

Your product on codecanyon appears to be doing quite well and has good reviews/sales [2] so you should probably market it more (if you're not doing so already). Also, building an ecosystem of free/paid plugins around it might be something you could explore. Finally, you could look into offering hosted instances for less technical savy users.

Good luck and keep up the good work!
