One of the best ways to make yourself happy in the present is to recall happy times from the past. Photos are a great memory-prompt, and because we tend to take photos of happy occasions, they weight our memories to the good.

One thing I wish I could tell my younger self: take photos of everyday life, not special occasions; later, that's what will be interesting to you.

Many people keep photos in their homes, in their office, or in their wallet, and happy families tend to display large numbers of photos at home. In 'Happier at Home,' I write about my 'shrine to my family' made of photographs.

Skillful conversationalists can explore disagreements and make points in ways that feel constructive and positive rather than combative or corrective.

The more I examine the issue of clutter, the more effort I put into combating it, because it really does act as a weight.

It's hard to avoid 'unconscious overclaiming.' In unconscious overclaiming, we unconsciously overestimate our contributions relative to others. This makes sense, because we're far more aware of what we do than what other people do. Also, we tend to do the work that we value.
