Final answer:
The author views Bob Heft's confidence and success with admiration, acknowledging how Heft's belief in his design led to its adoption as the official US flag with 50 stars.
Step-by-step explanation:
The author's viewpoint in "A Flag with 50 Stars" expresses admiration for Bob Heft's tenacity and belief in his own work. Despite receiving a less-than-perfect grade from his teacher, Bob Heft was confident enough in his design to submit it to Congress through his representative.
This act of self-belief paid off remarkably when his teacher's challenge turned into a reality, with Bob Heft's design becoming the official flag once Alaska and Hawaii joined the Union. The story conveys a message that young people's ideas are valuable and can have a significant impact, as demonstrated by Heft's successful flag design.
