Leave Art for Someone to Find

I've been leaving random notes a year ago across NYC. These notes/cards usually contains words of encouragement that my beloved mother has said to me in the past. I leave them at random places like subway stations, at the park and even at Starbucks. I don't expect my words to change someone's life drastically. But if it could help them in the slightest way I already feel that we are moving our world to a better place one step at a time no matter how long it'll take.
