Having a goal gives you the opportunity to measure the results. If you don't reflect on the goal after hitting/missing it, then it was pointless.
Maybe next year the goal should be 26 books. Or 100.
You don't know until you examine the value you got from pursuing the goal.
In other news, I almost read three books this year. I know I almost read them, because they are still on my nightstand next to my bed. In fact, they may be stuck there.... fused to the table... chemically bonded to one another.
I have no idea, because it has been so long since I picked them up.
I did read other books this year. But I couldn't tell you what they were, right now... completely slipped my mind...
