"You only live once, but if you do it right, once is enough." ~Mae West

Living right is by no means an easy feat. In fact, in the current societal atmosphere, it can be so difficult some do not even try. Personally, I try to start with the basics:

Water (1 Gallon a Day is a lot, but I figure as long as you have 1 bottle a day the rest of your fluids will still fill in.)
Food (Who really gets all their groups in? Still, add some cheese to a sandwich or with your grapes. If it can pair with wine there's no reason it can't pair with most fruits as well...)
Sunshine (No one says you have to live outside, but an hour a day does wonders - but remember to use your sunscreen this month!)

After that it's more of a social niceties, to be honest. I'm a big believer in cooking for people, but I know others whom enjoy reading for the elderly and mowing a neighbor's lawn just because they can.

If you're ever down, just remember that you can always do something nice for someone else and it will, more than likely, turn your entire afternoon around.
