Praemeditatio Malorum
In one line Rehearse one likely snag and one response, then stop.
Praemeditatio malorum, Latin for “thinking ahead about troubles,” is rehearsing a setback before it arrives. Seneca’s point is that surprise does half the damage. A prepared mind still feels the blow, and then it has somewhere to put its hands.
This is not rumination. Rumination replays the embarrassment and stops. Rehearsal names one likely snag and one response: what you will say, what you will check, who you will ask for help.
Keep it small. One snag. One response. If the exercise becomes a horror film you watch every night, you have left the Stoics and joined your anxiety. Shrink it until it is useful again.
Tomorrow’s talk

You speak in the morning. A useful rehearsal: the clicker may fail, so you will know the three sentences that carry the talk without slides. An unuseful rehearsal: forty minutes of imagining faces that hate you, with no plan attached.
Try this today Before tomorrow’s big task, name the most likely thing to go wrong and decide what you will do about it.
