If you have a thought while stepping out of a chair and forget it 2 seconds later, and if you have a thought and post it and get 20,000 likes, they're both thoughts you had and both are equally valid as thoughts. I feel like it's easy to feel like we need to "register" our thoughts as posts for them to count as being part of us but like, no - it's all part of us.
And I think when "registering" a thought was something that cost transcription, a stamp, and a walk to the postbox...
