The Stoics remind us that there really is no such thing as an objectively good or bad occurrence. Situations require our participation, context and categorization in order to be "bad".

Our reaction is what actually decides whether harm has occurred. If we raise our voice because we feel we’re being confronted, naturally a confrontation will ensue.

But if we retain control of ourselves, we decide whether to label something good or bad.

Marcus Aurelius was reminded that no matter how much he conquered, no matter how much he inflicted his will on the world, it would be like building a castle in the sand—soon to be erased by the winds of time.

Eventually, all of us will pass away and slowly be forgotten. We should enjoy this brief time we have on earth—not be enslaved to emotions that make us miserable and dissatisfied.
