This is a post on technology workers from Troy Hunt, but it could apply to many industries, and more of them all the time.
It’s perhaps more applicable in the technology industries, but I could see this applying to other places as well. The idea is that you shouldn’t be someone that comes to work, sits in an office and gets things done without ever making some mark in the world of what you do.
I think this makes some sense, but you don’t need to be out in the world making an impact publicly. However you need to document the places you do make an impact. You should have a whole history of projects, skills, whatever you’ve done.
If you do those privately, unpublished on the Internet, then make sure you have a private URL you can give to recruiters and prospective employers. Or a file you can send them.
