Answer:
C
Step-by-step explanation:
They are clear and measurable would be the correct answer because, in order to set a new goal, you don't want to phrase it as a question, it shows self-doubt. That strikes B out. Why set a goal if you already possess the skills for it? That's just lame. The whole reason to set a goal for yourself is so you can build as a person and learn and achieve new things. So the last option, D is out. Lastly, option A, having overly specific goals is just setting yourself up for failure. It may feel like the goal is too difficult to achieve and accomplish. Having a clear and measurable goal allows you to create flexibility and not be too hard on yourself for not accomplishing that goal sooner. I hope this helps you!
