Many thoughts from antiquity have pointed to them having a foreign origin, or warned one against allowing them power over oneself.
It certainly seems prudent to not "blindly follow" even your own thoughts.
However, there is nothing to mitigate your rogue thoughts except "other thoughts".
Which "thoughts" are "the real you"?
Perhaps none of them. I suspect that at most they can be influenced by the observer in us, which seems to (at times) command them through feeling. But we are entering a large area of speculation on my part now.
For all I know, the only thing about us that is us is the observer, along for the ride as these different forces all act through us. And by acting through us can seem as though it is us, due to the personal involvement we have as the observer.
We might be approaching the same conclusion.
"free-will" as a "fact" is logically-incoherent.
"free-will" as an e-motion (feeling) is like "love" (difficult to ignore).
