Brothers, sleep early and rise early. A few days ago, I stayed up late coding and felt lethargic and uncomfortable during the day. I've been adjusting for the past few days, slept at 9 pm yesterday, and woke up naturally at 5 am today, feeling energetic and refreshed. I urge all my brothers not to stay up late and to sleep and rise early. Additionally, if you need a free wake-up service, follow me, visit my homepage, and turn on account notifications by clicking the little bell icon. In doing so, every day when I get up and post a tweet, you'll receive a notification and can get up too.
