Sometimes our thoughts have shit for brains. I wonder if it could also be a process of trying to let the loud ones pass, regardless of origin; giving less energy to the ones that are immobilizing. Like the kid with his chin up, walking down a hall of kids taunting him (confidence).
Unless we are in a state of complete delusion or nirvana, how can we be all of our thoughts at any time when the minds are a web of gestalts and disconnected pieces. We are not always our thoughts (or our doubts), no more than we are an image held up to some measurable image by socially constructed milestones.
These constructs are so pervasive on social media, it can be hard not to compare ourselves on a writing platform but I wonder if we feel as defeated when we read philosophers or poets off social media. Do we feel as defeated by their talent? I know I do not. I accept that I am, like you, a perpetual student.
