The Hebrew word for Jew is Yehudi, which means to give thanks.
Thanksgiving should be a central point for every Jew and, in fact, for every human being.
Nothing is too insignificant to thank for.
The Rambam writes in connection with the festival of Sukkot the following:
[pay special attention to the verse in Deuteronomy, which describes severe retribution for showing a lack of happiness!!]
The happiness with which a person should rejoice in the fulfilment of the mitzvot and the love of God who commanded them is a great service. Whoever holds himself back from this rejoicing is worthy of retribution, as [Deuteronomy 28:47] states: “…because you did not serve God, your Lord, with happiness and a glad heart.”
Whoever holds himself proud, gives himself honour, and acts haughtily in such situations is a sinner and a fool. Concerning this, Solomon warned [Proverbs 28:10]: “Do not seek glory before the King.”
[In contrast,] anyone who lowers himself and thinks lightly of his person in these situations is [truly] a great person, worthy of honour, who serves God out of love. Thus, David, King of Israel, declared [II Samuel 6:22]: “I will hold myself even more lightly esteemed than this and be humble in my eyes,” because there is no greatness or honour other than celebrating before God, as [II Samuel 6:16] states: “King David was dancing wildly and whistling before God.”
