We traditionally wish each other "שנה טובה ומתוקה", a good, sweet year. So what's the difference between a good thing and a sweet thing?
As we believe that G-d is all good, all that He does and thus all that happens to us is inherently good. However, in our narrowmindedness and due to the lack of clarity of this world, we often find it hard to see this. Therefore we wish each other that we should have not only good years, but sweet years - goodness which is palatable to us.
I wish you all שנים טובות ומתוקות - good, sweet years.
