There are ebbs and flows in every aspect of our lives. Give in to the "funk" and take a break. Do not stress about "trying to get them all done". Remember, this is supposed to be fun and if you are not having fun, let it go, for now. You need a variety of experiences to refill your inspiration bank. If after a while, you realize that you do not miss it, move on. Life is way too short to feel burdened by a hobby.
