I don't feel like it
Why do you need to feel like something in order to do the work? They call it work because it's difficult, not because it's something you need to feel like.
Very few people wake up in the morning and feel like taking big risks or feel like digging deep for something that has eluded them. People don't usually feel like pushing themselves harder than they've pushed before or having conversations that might be uncomfortable.
Of course, your feelings are irrelevant to whether or not the market expects great work. Do the work. Ignore the feelings part and the work will follow.
