Your biggest saboteur is:
The High Achiever
You handle your online course like a peacock that wants to make its feathers look more and more beautiful. It can always be better or more beautiful.
The good news is that you can stop worrying about a lack of quality: your customer will certainly buy a valuable course. You are done with improving.
The trick is to ensure that your perfectionism doesn’t get in the way of launching your online course, while the quality of your course is (more than) good enough for the goal you want to achieve.
