“ When my mother didn't come back I realized that any moment could be the last. Nothing in life should simply be a passage from one place to another. Each walk should be taken as if it is the only thing you have left. You can demand something like this of yourself as an unattainable ideal. After that, you have to remind yourself about it every time you're sloppy about something. For me that means 250 times a day. ”
