"Souvenirs should spark joy when you touch them. Try to imagine if they will continue sparking joy in your life after you've brought them home," Marie says. "Once you finish tidying using the KonMari Method, you will gain a clearer sense of what sparks joy for you, and you will more easily be able to decide what you need in your daily life, including souvenirs. This decision-making ability will also prevent you from spending money on things you don't need," she adds.
