I never used to be a morning person, but honestly I prefer it this way now. I want to have the work done before my free time, and I want my free time to have as much daytime as possible. Following my current working hours has me awake when the sun is up, which personally gives me way more energy than doing stuff in the dark. I’d love to wake up later, but honestly that just wastes a nice part of daytime. You can train your body to maintain a schedule like this and then any other one will feel weird.
