first couple year of my professional work life, I was almost "awake" 18 hours of day. and similarly, in college time around 18-20 hours of all days of week.
@stpe Thank you for sharing your daily schedule. It sounds like you maintain a consistent routine with around 6 hours per day, primarily on weekdays. It's great to have that balance, and it's wonderful that you're flexible with your workload. Keep up the productive flow!
