Every day, before I leave home, I chant "phone, keys, wallet" which works well, but only when I remember to chant it. Fortunately, technology has advanced to the point where a phone can store digital keys and currency so I only ever need my phone. Before I travel, I chant "phone, passport, secret sling". If only they'd allow phones to store digital passports... Then I could put the phone in the bag and only need to chant "bag".
