I noticed that most poets produce probably only about 10 memorable poems in their lifetimes.

Not all of their poems are good. A lot of it is very mediocre…

The only exception is probably T.S. Eliot.

Maybe it's just a matter of my own taste, but the man has a good hit rate of 33%.

One out of every 3 lines of his poetry is mini masterpiece.

"Red into grey and tumble down

Late roses filled with early snow?

Thunder rolled by the rolling stars"
