Being an open-source maintainer is really hard. A lot of people tend to act very entitled towards you, as if you "owe" them your time or your attention.

It's totally illogical: you put something out there for free, and now because of that, folks feel like they deserve more of it! And yet this is often the prevailing mood in OSS communities.

At the same time, you may start to believe this logic yourself, leading to "open-source guilt." This often ends in burnout.
