How do you deal with creative exhaustion?

Full time wedding videographer here and one thing I didn’t expect when pursuing this career was how bad mental and creative exhaustion could be. Last year my wife and I did 20 weddings which I felt was pretty comfortable giving ample time between edits (my wife and I did 30 the previous year) but it feels like each wedding gets more and more taxing mentally, specifically during the editing. It’s not that I dislike the editing but the inability to be creative or inspired is difficult to work through sometimes. Does anyone else go through this? How do you manage creative ruts, lack of inspiration or motivation?
