     One of my closest friends has a family tradition that I quite like, and I've been slowly trying

to implement(实施) in my own family. Basically, each year after Thanksgiving dinner, all of the

people sit around in the living room and each person takes a few minutes and talks about the

thing they are most thankful about over the last year. Everyone in the family takes the question

seriously and answers it honestly, giving thanks for what really matters and adds value to their life.

     This is something I've actually thought about a lot in the last year, and I really came up with

two things, one obvious and one not so much.

     The first one, obviously, is the conception and birth and healthiness of my daughter. She's a

healthy, happy twomonthold baby who smiles a lot and very much enjoys sitting on her dad's lap.

I am so thankful for having this wonderful baby in my life, and thankful that she has the gift of

good health.

     The second one isn't my financial turnaround (as some of you might have expected-that was

what I was most thankful for last year). Instead, I am thankful for the discovery of the value of

writing in my life. A year ago, The Simple Dollar was only a few weeks old and was far from

popular yet-according to my data, on Thanksgiving Day last year I had about 60 subscribers.

The process of writing was bringing me enjoyment. This past year showed me otherwise, and I

am deeply thankful for it. After thinking about it for a while, I began to realize that it is a very

powerful and wonderfully positive exercise. You spend time reflecting deeply on the positives in

your life, and you often realize that even when things are bad, you do have lots to be thankful for

because there is a lot of good in your life, and it can shine a bright light even in a dark spot in your

life. I hope to repeat this each year on Thanksgiving, because it brought forth a pretty strong joy in

my life today.
