There's an excellent article by Rabbi Shmuley Boteach at the Algemeiner titled Absence of Gratitude is the Source of Rabbinical Burnout. It pays to read it and focus on whether we thank the people who we come into contact with.
Just a reminder that today is the 2nd of the two Rosh Chodesh days of Tevet, so don't forget Yaaleh V'yavo, Musaf and a full Hallel.
Wishing you a good Chodesh and a happy Chanukah. And go ahead and thank someone.
