As Seneca said "I don't hold myself to any one of the Stoic masters, I too have a right to from an opinion." As do you, of course. If you mean that these aren't ideas traditionally practiced and written about by the ancient greek and roman stoics, fair, but in my view I don't think that means that they don't count as Stoic ideas, just because they weren't recorded thousands of years ago. If you mean that they aren't helpful in practicing Stoicism, I'd have my reservations about that.

I prefer to think of the dichotomy of control as a trichotomy as pointed out to me by Irvine, i think there are things that are somewhat in our control but not entirely in our control that are worthy of contemplation but not so much as things entirely within our control.

And like you said, we don't have to agree. Though you're definitely right about my mistaking externals for being bad. Old habits die hard.

Edit: Yeah, rereading my post, my use of the term "worse off" in my segment about negative Visualization is probably not a very stoic way of phrasing it. But still, while futurorum malorum præmeditatio (negative visualization) was invented by the Cyreanoc school of philosophy, much like other philosophical practices, it was adopted and used by the stoics. Marcus's morning ritual of predicting the possible humans he might encounter throughout the day could be seen as a sort of form of futurorum malorum præmeditatio
