I'll probably be adding to this final list this weekend, but I'm all out of ideas at the moment. :)
And just one last little last thought... Sometimes I think making others happy really makes you happy. When you really do something nice for someone & make their day, you sort of get this great little feeling inside. (haha is this a selfish reason for doing something good?!!! ;) But really, I've noticed that when I'm out & I smile more at people & connect more with others, it puts me in a better mood.
