If we have no essence - is it hormones that guides us....?
If we have no permanent or separate self, we probably would change quite often. And we do... Our mood swings not just with aging - less testosterone in men and more in women - but also over days or weeks. So the teenager and the old man cannot be really the same... But some things in us seems to remain the same - do you for instance like the same music now as when you were seventeen? Or some of it? Or maybe some music are timeless... (doesn't matter what genre) ? Anyway - in this guys there are many hormones acting - but there must be something more... I suppose we are not just matter.... For instance - what is music?
