I would say that such a moment in recent memory was the day I graduated with my Associate of Science degree. Starting college at the age of 50 was a fearful endeavor on my part, with no clear image of the end result. I had never been to college, as that was not an option that was available to me when I finished high school. I did not know what to expect, what it entailed, or if I could even accomplish the task.
I not only graduated, I completed the two-year program in only sixteen months with a GPA of 3.9. I was and am proud of what I accomplished.
From one who knows, it is NEVER too late to start over, try something new, and succeed!!
