“Noticing new things” is actually Ellen Langer’s definition of “mindfulness”. It is, however, a big help in a curiosity quest.
This week I am working out at the UN in Vienna. Some rich ground for curiosity practice is the artwork there. Member states send contributions to mark special occasions and so there is a lot to see. I became aware of that (again) leaving the building this afternoon. Tomorrow I’ll try to post some photos.
