Trace a square with your attention: inhale four counts, hold four, exhale four, hold four. Match the rhythm to footsteps or flashing platform lights. If distraction pulls you away, return kindly to counting. One quiet circuit can replace a sigh with steadier shoulders and clearer eyes.
Right before doors slide open, take two deliberate breaths. On the first, feel the belly rise; on the second, soften the jaw and brow. Let this tiny pause reset your pace so you step out attentive, neither rushing nor dragging, ready for the next moment exactly as it is.
