I'm a freelance developer in the WordPress space. I've been using my personal website to attract leads for 11 years, and recently decided to teach what I know in my video course, "The Personal Website Playbook".
I gave myself the month of January to complete this project. I launched it last week and it's made ~$10K in sales so far: https://twitter.com/tom_hirst/status/1359067774056816641
Alongside freelancing, I've been creating info products for 10-months. The revenue from digital product sales hits different to that which you get from trading time for money!
If you have any questions about what I've learned, just ask. I'll be happy to answer them all.
