Crossed 100$ in total sales

Launched this course 10 days back & I touched 100$ in sales today. Not a big number but gives validation for a niche demand.

How?
Got in a total of 7 customers who purchased this course. The sources which worked for me were Indiehackers (2 sales), Personal Network (3 sales), Hacker news (1) & one Unknown.

This month goals are to figure out the distribution channel which can be consistent & get initial feedback for the course.
