As a zodiac sign known for their wittiness and sense of humour, Sagittarians are unlikely to have problems with getting in a good mood in the New Year. People around you will still appreciate your cheerful approach to things, your creativeness and ability to remain optimistic in any situation.
But keep in mind that words have a great power; be more careful about the things you say. A careless joke may offend somebody who is special to you and you most definitely don`t want it, do you? So watch every word you say, and listen more to people around you.
