There isn't always a sense of wonder in creative work. Sometimes it is drudgery, just like any other kind of work. In the past 20 years since I started writing and editing professionally, lots of that time has been without wonder, though still wonderful. The wonder comes at unexpected moments, often when reading someone else's work, sometimes when reading my own, and even at times not related to reading at all. Wonder is everywhere, with loved ones, in the garden, with my dawg...
Deliberately keeping wonder in work could be tough. God knows I work my bliss, but even so, it takes discipline to create wonder.
Best wishes,
