Defining work boundaries in a small home office helps your brain associate a specific space solely with productivity, making it easier to switch on focus during work hours and switch off afterward. Even if the workspace is small, having a dedicated corner or niche signals psychological separation from daily living areas. This separation reduces distractions and promotes work-life balance. Practical steps include choosing a consistent workstation, organizing supplies, and tidying the area daily. Clear boundaries prevent your home from feeling cluttered by work and improve overall mental wellbeing.
