Cocccinelle, I actually prefer "If a job's worth doing, it's worth doing badly." If you think about it, this does not mean that you OUGHT to try to make a mess of it, it means you should give it your very best shot, no matter how bad that turns out to be. In other words, "If it's worth doing, it's worth doing"...end of story.
Hi quizmonster, I know what you mean but I think the job's worth doing well; even if the result isn't good, you've put all you've got into it. I also agree redman with that; especially when it comes to computers - leave it be - they have minds of their own. Still working that one out brenda!
