The Gap Between Stimulus and Response

When something hits you — an email, a conversation, a moment of stress — your system doesn’t think first. It reacts.The fast pathway (your survival response) Why this matters more than we thinkThis is also why I’m intentional about something that seems simple: I don’t live in my email.Because every “ping,” every notification, every glance […]
