Dip or hamster wheel?

I'm currently reading one of those self-help books for entrepreneurs by Seth Godin, called "The Dip." The Dip is a stretch of time for creatives, business people, etc., that you go through in your career, but that sometimes makes you feel stuck, but that, even when it seems difficult to keep going, you do. You're experiencing The Dip, according to Godin, the time when you are learning and honing your skills and promoting yourself.  Going through The Dip can take years of hard work. The opposite of being in The Dip is being in a cul-de-sac, or, if you prefer another analogy, a hamster wheel, where you keep running in circles, or find yourself in a dead-end cul-de-sac going round and round with nowhere to really go. So, the premise of the book is do you work through The Dip, or realize that your're in a hamster wheel/cul-de-sac and go on to something more suited to your skills?  Once you get through The Dip, it's supposed to get easier, you just have to stick with it. I feel like I've been through a lot of dips in my art journey, but probably more hamster wheels, truth be told. It's probably why I sometimes go from style to style, trying to find the one that suits me and my personality best. So, think about your creative endeavors or business strategy, and ask yourself if you're Dipping, and working through The Dip, even though it might be tough at times, or ask yourself if you're in that wheel, spinning around and getting nowhere, and maybe it's time to change your focus. I'm sharing a small piece that I'm working on that has a "dip" in it, and I wonder if if I put in there subconsciously. Hmmmm... Comments always welcome! Tell me about your dips or cul-de-sacs.
