Is it good to tell others everything about your writing? Sometimes, it’s not. One may face people who wish they could get your job. Why stoke their flames by saying you’re doing this and that?
Otherwise, one may select what one tells others.
It’s a good thing to remember the proverb of concealing what one knows. Not only in terms of facts and subjects, but in what one does with their time and how this applies to writing.
A little mystery where appropriate can give a colour to your profile, whereas saying everything you know lacks discretion.
