Creativity is a muscle, it must be used or it can atrophy. It doesn't mean you can't connect again, it just means, "Practice makes perfect".
If you, as an artist allow your paints to dry out, can they be restored? Perhaps in some cases and in others, it may be best to buy a new set of paints, to start fresh. It doesn't mean the talent is gone away only that the tools through which the artist expresses his talents, needs refreshing or to expand and use new tools.
