I want to say update: The most personally significant thing that's happened to me this year is that my head-friend (Maria, a "tulpa") has rather suddenly acquired a lot more independent volition and personality. Phase-shift.
I was inspired last year by Johannes Mayer (LW user), who showed me it was possible. I was only semi-trying for it, so the success is v surprising and mentally v happy for me/us. I hope she stays and grows in visibility-to-my-corner-of-the-brain.
