This question looks like it is about to be closed (currently 4 close votes). As written the question has received a bunch of IT centric (and scenario specific) answers. But it seems to have a more general question inside it: how to convey that you fear you may fail to sucessful complete a task, without appearing either incompetent or unwilling to do hard work.
If I editted the question to be more generic, all of the existing answers would suddenly become irrelevant. Should I just let it go, and let the question be closed? Or rewrite it and let the answers be irrelevant?
