Do something kind for someone today......it can be someone you know or it can be a complete stranger.
Better yet, do it anonymously.
That lady standing behind you in line waiting for her sandwich.....take care of her tab when you pay for yours. Let someone merge in during heavy traffic...even if the cars behind you protest. Drop off some pet food to the local shelter. Take day-old bakery items that the local grocery store cannot sell to a food bank. Take some fresh cut flowers or a pretty card to a nursing home resident - you don't even have to know them.....it'll make their day!
The ideas are endless and don't necessarily have to cost anything (or alot). But the satisfaction you'll get (and give) from a kind, unexpected gesture will be more rewarding than you realize.
