Mental block in adding value and creating content

When I get ready to create content or add value by posting something of value on my own social media, I get into these mental blocks. I know it’s because I’m thinking, what would be super valuable to talk about right now? Then I indulge in confusion. I think I just need to sit down and force myself to think about what to write, but I feel a lot of resistance to that. Resistance to writing something.

Probably because I have the thoughts, I have nothing new to add, I have nothing valuable to add, all the great content is already out there, why would someone want to read/listen to what I have to say. Then I get into imposter syndrome and stop taking any action at all.
