I definitely agree that quality is more important than quantity; perhaps I could have made that clearer. My point is that with marketing, you can get a lot of talented people. If you are running a general course, you probably couldn’t only attract people who are in the 99th percentile, but you will get some, which makes the whole endeavour worth it (you can also try your best to filter out less promising people depending on your bar and ability to take participants)
