Read this passage from edgar allan poe's the raven
ah, distinctly i remember it was in the bleak december,
and each separate dying ember wrought its ghost upon
the floor.
eagerly i wished the morrow,-vainly i had sought to
borrow
from my books surcease of sorrow-sorrow for the lost
lenore-
for the rare and radiant maiden whom the angels name
lenore-
nameless here for evermore
which series of letters represents the rhyme scheme of this passage?

answer: i would say he was very determined and persistent in overcoming obstacles.

explanation:   "the magician of menlo park" as he was called, liked to tell an incident that happened when he was 8 years old and came back home crying after attending school for three months because his teacher called him "sterile and unproductive". from nowadays perspective, we can say that thomas alva edison was one of the most persistent and determined man that has ever existed. when edison was 14, he contracted scarlet fever. the effect of the fever, as well as a blow to the head by an angry train conductor, caused edison to become completely deaf in his left ear, and 80-percent deaf in the other. so as you can see he had to struggle to not so many minor issues but he always succeeded.
