Final answer:
Andrew is missing the value of creativity and generating a variety of ideas.
Step-by-step explanation:
The point that Andrew is missing is the value of creativity and generating a variety of ideas.
Brainstorming about goals is not necessarily about coming up with realistic ideas right away, but rather about exploring different possibilities and expanding one's thinking.
By generating a variety of ideas, even if some may not be realistic, it allows individuals to think outside the box, challenge themselves, and potentially discover new solutions or approaches that they may not have considered otherwise.
