I think one reason is that many of us do not learn from the old year. What did we do? Why did we do it? Did our decisions and actions achieve the results we wanted? If not, what could we have done differently? What worked, what didn’t? What have we learned?
If you truly want to achieve your goals for 2017, I suggest you first think very strongly and clearly about 2016. Use that knowledge to develop goals and plans for 2017.
May you learn from the old to create the new!
