     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.
