Setting clear boundaries is essential for maintaining focus and productivity, particularly in situations prone to interruptions. Effective signage, like 'do not disturb' during recording, can help communicate these boundaries in advance. It's crucial to remember that the concept of 'I can't' transcends physical impossibility; it encompasses mental and emotional limits as well. While at home, one may feel the temptation to respond to interruptions, it's important to recognize that true availability requires psychological space, energy, and time. Just as one recognizes physical constraints in an office environment, similar respect must be applied at home to safeguard what matters.
