Cynicism masquerades as wisdom, but it is the furthest thing from it. Because cynics don't learn anything. Because cynicism is a self-imposed blindness: a rejection of the world because we are afraid it will hurt us or disappoint us. Cynics always say 'no.' But saying 'yes' begins things. Saying 'yes' is how things grow.
