LI is definitely a long game and you're right that content creators are flooding LinkedIn with their systems and tips to achieve XYZ. It's really exhausting to try to follow it all.

My strategy is to not follow content creators but people who think and have their voice. So not course creators or LI writers really. These I unfollow and focus on business leaders who have something interesting to say about what I am after.

Maybe instead of posting, how about you join some conversations? It's a bit less demanding and you can still share your thoughts and build friendships.
