7 Ways to Be Happier at Home

In my new one-minute video book trailer, I list "10 ways to be happier at home." Some of those suggestions are serious, and some are goofy (to my surprise, my suggestion regarding purple has turned out to be fairly controversial). Here's another list of ways to be happier at home -- or, at least, that have made me happier at home.

One of these items is important enough to be listed in both places. Can you guess which one?

1. Get enough sleep.

2. Embrace good smells. No cost, no calories, no energy, no time -- a quick hit of pleasure.

3. Cultivate a shrine.

4. Accept yourself, and expect more from yourself.

5. Give warm greetings and farewells. I was surprised by how much this resolution changed the atmosphere of my home.

6. Abandon your self-control. Well, this one really works for my fellow abstainers, not moderators.

7. Remember the Sixth Splendid Truth: The only person you can change is yourself.

What else would you add to the list?

The photo above is included in Happier at Home. As a confirmed under-buyer, I almost never make impulse purchases, but last fall when I saw this Christmas ornament, a tiny model of the "Play Family" Fisher-Price house that my sister and I played with for years, and that my daughters play with now, I had to have it. I love miniatures, and it seemed like the perfect memento to keep in my office as a reminder of the time I spent writing this book. Plus, the doorbell actually rings! Who could resist?
