Most successes are unhappy. That's why they are successes - they have to reassure themselves about themselves by achieving something that the world will notice.
The suffering and calamity are, moreover, exceptional. They befall a conspicuous person. They are themselves of some striking kind. They are also, as a rule, unexpected, and contrasted with previous happiness or glory. A tale, for example, of a man slowly worn to death by disease, poverty, little cares, sordid vices, petty persecutions, however piteous or dreadful it might be, would not be tragic in the Shakespearean sense.
Things are simply the way they are. They don't give us suffering. Like a thorn: Does a sharp thorn give us suffering? No. It's simply a thorn. It doesn't give suffering to anybody. If
we step on it, we suffer immediately.
Why do we suffer? Because we
stepped on it. So the suffering comes from us.
