Answer:
Yes, the idea of myself five years from now has changed since I began the course. Before taking this course, I was aware of what i wanted for myself later on down the line, but I wasn't sure about how to go about achieving these things. However, after beginning this course, things have changed. Partly because I now know how I can achieve the things that I was aware I wanted before beginning this course. But it has also changed my idea of myself five years from now, because it has also made me realize there are tings I want now, that I wasn't aware that I wanted before taking this course.
Explanation:
It's going to differ person by person, but I am enrolled in a K12 school and had the exact same question recently. I've provided you with the answer that I submitted, make sure to make any changes that you need too in order to make it more personal that way it comes across as your own work and not someone else's.
Again, mine is just an example. Please do not submit my answer word for word as that is plagiarism and can be traced and lead to you getting in a whole bunch of trouble.
