I ran across this reading recently and these 3 things in particular stuck out to me; I think they're helpful advice for daily living. And, I like the suggestion that they become habits, perhaps over the new year:
Let go of your results.
The big enemy of happiness is worry, which comes from focusing on events that are outside your control. Once you've taken action, there's usually nothing more you can do. Focus on the job at hand rather than some weird fantasy of what might happen.
Turn off "background" TV.
Many households leave their TVs on as "background noise" while they're doing other things. The entire point of broadcast TV is to make you dissatisfied with your life so that you'll buy more stuff. Why subliminally program yourself to be a mindless consumer?
End each day with gratitude.
Just before you go to bed, write down at least one wonderful thing that happened. It might be something as small as a making a child laugh or something as huge as a million dollar deal. Whatever it is, be grateful for that day because it will never come again.
