Park Bogum reveals things he does before bed!

 In the latest episode of Lee Hyori's Homestay, Park Bogum was asked what he does before bed. He revealed that he writes diary every night, to reflect things he has done in one day.

 He then added, 'huge mistake can be remembered, but small mistake is forgotten easily, so I jot them down'.

 Is this a good daily routine?
