I do love to eavesdrop. It's inspirational not only for subject matter but for actual dialogue the way people talk.
If I didn't try to eavesdrop on every bus ride I take or look for the humor when I go for a walk I would just be depressed all the time.
I envy people with dreams and passions but I don't think that way. I still don't have a 'bliss' to follow. For people like me - I suspect that's most people - holding out for a 'dream' or a 'passion' is paralyzing. I just like having work I enjoy that feels meaningful. That's hard enough... but it's enough.
