Passage Two
When I was 65, I decided to go back to school. I realized this was the step toward bettering my life. It was merely an idea, and when it was time to take action, a community college named Rock Valley College stood out as a great fit for me. The reasonable cost and location of the main campus meant that I could attend classes without seriously affecting my family’s finances. My family noticed a change within weeks; I was happier, more organized, more focused. My workload forced me to manage my time more wisely and work more sufficiently. I felt confident, ready to take on new academic challenges and fill in my knowledge gaps. However, the changes I’ve experienced run deeper than that. There is a renewed sense of curiosity and a desire to learn in our house --- not only for me, but also my children and husband. Within the excellent professors and great classes at the college, it would have been difficult to pass these lessons on to my children. “Education is important” would have been just words, instead of a way of life they now see. The example I set sends a stronger message: Pursue education with passion, and happiness will follow. The college has made it possible for me to reach my potential and set higher goals for my life. Going back to school has enriched my entire outlook on life. Anything is possible with an education; I felt that from my first day at the college and still believe it today. My community college has most certainly changed my life for the better, and I even made a few friends.
