Are goals important?

Why? I chose some, but it was more to give focus to thought, making it more pleasant, than for any other reason. My energy is low lately - still recovering from surgery and so on - so it does not make me follow through on my goals. But I know what they are. I decide not to add more, or to send my limited energy off in other directions. "Do these things, or rest." That is how goals are helping me, so I don't revisit the question endlessly. Goals help me not think. Very useful!
