Working from home
has the extraordinary benefit of giving you control over your day-to-day. You can wake up, work, exercise, and eat whenever you want to, free from the socially enforced norms of the office.
But, with great power comes great responsibility. Make sure you define boundaries, both with yourself and those closest to you. Pick the time of day when you’re most productive, and get your 1-2 hours of productive work in during the day at minimum. Make that as fundamental to your routine as brushing your teeth.
TLDR; program your life, or it will program you.
