To me, it is a balance of both.
Life is definitely what happens to you. That alone is strikingly important, as much of it is not stuff you have any control over. You are quite literally a victim of most of life.
However, how you react to what you can control is also critical in dealing with it, in that you can identify things you can very much directly affect in some way.
Stoicism includes the ability and skills to tell the difference between the two, coping with the former as best as possible (to retain your mental health), and actively strategizing on how to deal with the latter as effectively as possible in order to minimize any negative outcome or maximize positive outcomes.
I have a tube-based distribution system from the second-floor window that I started using during COVID to keep my distance from those plague incubators that came calling, and just never stopped using it.
I live in a moderately cold climate, and Halloween evening nearly always drops to around -5℃ to 5℃. So it’s much nicer to just sit in a cushy armchair by the window with a warm blanket over my legs and drop candy through the tube. A surprising amount of adults, teens, and tweens are tickled pink by that system, although a lot of little kids need a surprising amount of direction to get their candy.
And yes, I always drop either two pieces or - for those in dark hoods and carrying scythes - full-sized snickers.
