It is the final day of the year, yet if it’s not the final day of your life, it ought to have a different meaning. The passing of the year is symbolic, and need not signal the end of anything, unless it was the end of a school term.
For your projects, each needs to end when it needs to, not when the calendar year ends. I wish you a joyous 2023, and strength to continue on your journey. This is not the end.
