Got in shape and it changed literally everything
Started at 280 pounds and completely out of shape. Couldn't play catch with my kids without getting winded. Joined a gym three years ago just to prove I could do something for myself. Lost 85 pounds, ran my first 5K, then a half marathon. But the physical stuff was only half of it. My confidence came back. My marriage got better. Got promoted at work. I sleep better. I smile more. I'm not the same person. Miss my old eating habits sometimes not gonna lie but I don't miss how I felt.
Getting in shape as a dad hits different when you realize it's not just about you anymore. Sounds like you nailed it.
