(1) nourishing a hobby of reading good books ->nourishing the hobby of reading good books?
I feel ambivalent about this one, either way seems to be OK.
(2) the more rewarding is the reading -> the more rewarding the reading is ?
actually, should remove the "is".
(3) also they benefit from it -> they also benefit from it ?
I totally agree with this. I don't know what I was thinking.
