Less really is sometimes more and will leave room for that holiday spirit to come freely from your heart, rather than as a 'performance'. Remember that the holidays do not mean the same things to all people. Remember too that each person has different needs, even within a family unit. Consider the belief systems, needs and situations of others. In a variety of ways, holidays are times of high stress for many people.
More people tend to feel sad, depressed and overwhelmed.
Many feel lonely, even when in a roomful of people. This is especially true when the year has brought major life changing events, such as job loss, the death of loved ones, divorce, illness, or other changes in life status, such as being an expat, or being separated from family. Make it a comfortable invitation for them to accept, but don't force them. Simply reach out with sincere generosity of spirit. Reaching extends in both directions.
