My friend told me that Chanukah is a minor holiday, unlike Rosh Hashanah and Passover, and so we shouldn't make such a big deal out of it. He said that the only reason it became so big was because of the season.
Unlike Rosh Hashanah, Passover and other "major" holidays, which are biblically prescribed days of rest, we go to work on Chanukah. Even on Purim, going to work is not recommended. Also, on Jewish holidays we wear special clothes. But the days of Chanukah are regular workdays in regular clothes.
Yet Chanukah is a hardly a "minor" holiday. Read what Maimonides writes in his Laws of Chanukah:
The mitzvah of kindling Chanukah lamps is a very precious mitzvah. A person should be very careful in its observance to publicize the miracle and thus increase our praise of G‑d and our expression of thanks for the miracles which He wrought on our behalf. Even if a person has no resources for food except what he receives from charity, he should pawn or sell his garments and purchase oil and lamps to kindle them.
Maimonides continues by instructing that if one has only enough money to afford either a cup of wine for Shabbat kiddush or oil for his Chanukah lamp, the mitzvah of Chanukah takes precedence. Doesn't sound too minor to me.
Especially when you take into account that this is what Chanukah is all about: to "light up the darkness" (which is why we light it at night, at the door or window). So even though its a regular workday, well, that's really the whole idea: To light up the regular workday. And that takes a very special light.
At any rate, since when do we look for excuses not to celebrate? On the contrary, in the words of wise King Solomon, "A good heart always celebrates."
