The first note to make would be that I am not sure you have the interpretation of passiveness in Stoicism right. If anything the Stoics used this exploration of what is or is not in our control for to 'overcome' and take control of certain issues in life. As well as this, I do not believe using Holliday as the bastion of Stoicism is correct. The way I describe his books on the Stoics are someone who has put a garishly green bath in an otherwise nice bathroom suite. His takes on Stoicism are not terrible, far from it, but it is clear he writes for mass appeal and it is very clear he comes from a marketing background. To what extent he is disseminating Stoicism and/or vacuously marketing for mass appeal in his obnoxiously cringe LinkedIn style of marketing techniques is a line he rides; I do recognise this may be a that is generally my own, but I would say reading core texts yourself if far more fruitful than his works (which is a given).
