If you want to eat, eat. Your body needs food.
If you want to sleep, sleep. Your body needs sleep.
If you need to do something for your mental health? Do it, your mind needs care.
If you want to workout, workout. It’s good for you.
If you want to work hard on a project, work hard. The sense of accomplishment you get from hard work is great.
Do any of these things, it’s your choice. But don’t let your view of the things you need be altered by things you might want to do, and don’t let anyone else tell you how to earn those things. You don’t have to earn food and rest, they are a required part of being a human. You’re allowed to be human, no matter how hard you workout.
