I write code every day. Depending on the day, how I'm feeling, what I'm working on, etc, I'll spend more or less hours doing it. Every day I hit a wall where I'm done coding for the day and I've learned to embrace that. My brain and my body just say "stop working" and I do. Sometimes I hit that wall after 4 hours, sometimes I hit it after 12 or more. I've learned that if I try to push myself to work past that wall, my work becomes lower quality and I don't really pay attention to what I'm doing.
