You need to be prepared

From Stoicism to the Jedi, preparedness is an antidote to stress

“Everyone faces up more bravely to a thing for which he has long prepared himself, sufferings, even, being withstood if they have been trained for in advance. Those who are unprepared, on the other hand, are panic-stricken by the most insignificant happenings.” - Lucius Seneca (4 BC - 65 AD)
