I started reading this because I had read a later article of yours which I entirely disagreed with. It was going well. And then you wrote “If being consistently creative is draining to you, or if it depletes your mind and you aren’t able to recover within a reasonable amount of time, consider that it may not the right path for you.”
One of the top Creative Directors in the world regularly takes 1 year breaks every couple of years completely way from design. Because if he didn’t he wouldn’t be able to keep creating the award-winning work that he does. Another creative I know runs a top ad agency and he’s had multiple burn outs. But his work is top notch and he continues because he loves what he does and he’s amazing at it. My point is, you cannot be 100% switched on and productive every single day of your life. You will have off days. You will have sick days. You will have days when your work isn’t amazing. You will have moments (many moments) when you want to throw in the towel. But that doesn’t mean you should.
BTW, even Stephen King has had writer’s block. And that’s ok. He’s human like the rest of us.
