I don't usually make didactic pronouncements (I offer suggestions and helpful hint!), but here goes.

These are the New Year's resolutions I wish everyone would make:

• Begin each day with a confirmed intention to do at least one kind thing.  It doesn't have to be huge. Let someone go ahead of you. Say thank you (and mean it) to the clerk at the post office.  Call someone who needs to hear a cheerful voice.  Give an honest compliment.
• End each day by identifying at least one thing for which you are grateful.  Beginning day focused on acting kindly and ending it focused on gratitude will help make happiness your default setting.
• Use less, give more. 
• Before you pass on that email (or tweet or blog post, etc.), check out the veracity.  (I use www.snopes.com).  I get at least one email a week that is spreading a rumor.  Isn't there enough nastiness in the world without our adding to it?
• At least once in the year ahead, open your home and your heart to another human being.
• Absent evidence to the contrary, assume the best of people –including yourself.  Yes, some people will disappoint you and you might make yourself vulnerable, but you'll also be open to wonderful opportunities. And think of the time you'll save by not beating yourself up over an honest mistake!
