The Indians have (afaik without reference to our leader) coined the splendid word "prepone" as an opposite of "postpone"; so let us here do the same.

The opposite of "exceed" is clearly "subceed". Google produces 29 non-redundant results; some of which are clearly misspellings of other words; but some intentional antonyms.

I shall henceforth use "subceed" on all possible occasions. eg in autobiography - "he routinely subceeded early expectations"
