Adding to what the others said.
Wonder, comedy, and curiosity all keep me rather entwined.
As another matter though, the feelings of the writer is very much noticable. Robert Frost once said,
"No tears in the writer, no tears in the reader. No surprise in the writer, no surprise in the reader." and the man certainly had the right idea.
Unpredictability, impressive prose, and originality are also highly commendable in my book.
I can't help but feel compelled to quote countless of my favorite poets, authors and writers, and whilst as I could in my own words go on at length on this subject, i'll cut this short.
You get the picture, and I won't be a windbag.
