I have chosen "Create CPAN distributions". Because I have written at least a dozen modules, probably more. OK, most of them are really specific to my firm's environment and would have little general interest, but at least 3 or 4 of them could be useful to the more general public. Except that, so far, I haven't taken the time to learn how to make a CPAN distribution.
