Why doesn't the life you used to dream of feel like it’s yours anymore?

You wouldn’t call it a crisis necessarily, but maybe feeling disconnected and chronically tired, and feeling like you’re going through the motions in rooms where you are, technically, succeeding. You have arrived at the destination and found yourself still waiting for the feeling that was supposed to come with it. Have you burnt out on your own goals? Is it supposed to feel different? Is this all there is?
