What Is the Hardest Part of Being an Internet Radio DJ?

Based on what I know , I think the hardest part is consistency. You must show up every day, at the same time, whether you have 5 listeners or 500 or you don't even have active listeners yet, you have to maintain consistency. Another issue is building audience. With the way Spotify, YouTube, and podcasts are competing for attention, to keep people tuned to your live stream is hard. Who is an internet radio DJ here? How do you survive?
