Every day you write down X things you are grateful/thankful for. The goal is to write new things every day.
The intent is to help you rediscover things in your life that you tend to take for granted. A lot of us have it pretty good but still feel sad or depressed day-to-day. This journaling process intends to curb that.
I tried this for a while, via daily tweets instead of a journal. Tried to find one thing a day, even if it was the smallest of things (e.g. first time wearing a new pair of socks!).
Very quickly I found out that my daily gratitudes are about (1) driving to/from work that was less congested than usual. (2) finding a good parking spot (mostly at work).
(3) getting a tasty lunch (during lunch break, at work).
This actually depressed me, b/c it was just further indication all I do is work.
I do a form of this is a "monthly reflection". Daily made me feel "beholden" to it, whereas once a month feels like something to look forward to.
I share it with close friends as a way to connect. Feel free to email me and I can send a sample, but I'm not gonna directly link on the internet as it defeats the purpose :)
