It is so much easier to dream grand dreams. And save the world in your thoughts than it is to get dirty and be used.
It's far prettier to touch a life in your heart, and launch an effort in your mind than it is to adopt an orphan. Or reduce your paper waste.
It's the stinky, smelly people, ungrateful persons that we meet in the alley that need our attention. Not the beautiful helpless creatures in our daydreams.
