Be a happy person

"Rejoice in the Lord always; again I will say, Rejoice."

Philippians 4:4 (ESV Bible)

Happiness: It Really Is Contagious (audio or text) by Allison Aubrey.

If the result of the recent study by researchers at Harvard University and UCSD is credible: a friend living close by a happy person has a 25% higher chance of becoming happy, a spouse 8%, a next-door neighbor 34%, and the entire social network up to "3 degrees," then one has a very good reason to choose to live every day happily not grumpily.

But can one really choose? Yes. The Bible verse above implies so and says how, as Christians are exhorted (or "commanded," with the grammar and syntax of the original language, I was told) to rejoice always.

This is my struggle or lesson of the week.
