-practicals could be fun. 
+Do you remember that creative and bright mind willing to learn all sorts of tech to build cool stuff and become a maker? I wanted to build an arc reactor and an Iron-Man suit. My uncle and I used to talk about it so much (he _used to_ love engineering). Thats when I choose to be an mechanical engineer. I grew up and I developed a fondness for air crafts, rockets and everything that flies. that is when I decided to become an aerospace engineer. The reason for choosing to study computer engineering was due to my natural fondness for the computers (one of the few more reasons).

+Creativity is an important learning outcome from an engineering college. That's why even though I am not the best creative person I know, I value music and art as much as anything else. STEM is important, but creativity within how that STEM is used by the eventual adult makes it even more valuable.
