Micky stood at the mailbox, her hands shaking with
anticipation, nerves, and excitement, as she prepared to mail her
application to one of the most prestigious universities in the
nation. She had worked diligently her entire academic career to
get to this point; she had taken the most rigorous courses in high
school, from advanced chemistry to trigonometry, and aced each
one. She was no Einstein, so she had put every ounce of energy
into her studies. She had participated in as many extracurricular
activities as time allowed. Her effort had two purposes: to get into
this college and to earn as much financial aid and as many
scholarships as possible. Sometimes she felt she had the weight of the world on her shoulders, but when she received her acceptance letter, she knew it would all be worth it.
