This is not nice but it is kind:

Nobody owes you their attention. If you’re spending your time complaining about engagement and getting crickets, it’s time to face the reality that your output isn't good enough yet.
Neediness is a repellent. When you post to be validated, you act as a taker, and maybe you’re not aware that desperation is obvious to everyone else. Shift your focus. Stop asking the network what it can give you, and start building. "Be so good they can't ignore you."

The market is efficient: If people aren't interacting, or they are interacting in a way you don’t like, you’re not providing value. Full stop.

Attention is earned, not owed. Stop complaining. If you can’t figure out how to thrive here that is not anyone’s fault but your own. It’s sink or swim.
