Even though the end of one year is simply a number, it's hard not to fall into the trap of trying to determine where one has been in the last year, where one is going in the next, and whether or not things are "better" or "worse" than they were before.

Then, of course, we fall into the trap of trying to quantify it. Unfortunately, the truly important things in life cannot be quantified. There is no equation to calculate happiness, contentment, fulfillment, joy, or love. So, what do people do? They attempt to equate their happiness with things that can be quantified, such as salary, vacation days, cars, houses, possessions, food, status, fame, and power.
These things are not happiness. As soon as something is quantified, realize that it can be taken away, and what would one be left with, without salary, possessions, or status? Nothing.
"Let your way of life be free of the love of money, while you are content with the present things," Hebrews 13:5

"Happy are those conscious of their spiritual need… hungering and thirsting for righteousness, since they will be filled," interpolating Matthew 5:3, 6
