When your creativity is waning, the most likely change needed is that of your own mindset. This could look any variety of ways. Two are strong possibilities. 1. You are Jealous Unless a speaker or writer really really impresses me or makes me think differently than I had before I heard them, I am generally dismissive of them as a speaker and author. Two things I have not pursued or gone after! But something in me is dismissive and unimpressed.
This thing within is jealousy. Jealousy is basically a part of you that is convinced there can only be one of something, and you are not that one.
The problem lies in that most things can have more than one of them. It is possible for there to be more than one artist within whatever artistry you pursue. But that part of you that gets FRUSTRATED when someone else accomplishes something you know you can do is jealousy.
2. You Don't Dream This is just simple psychology. I have read of a few different studies that show our minds are their most creative when they are allowed to disengage from the rigidity. Our brains are most creative when they are allowed to wander without force. Set time to make that happen!
What mindset change needs to happen for you to be more creative?
