I’m 25. I’m getting far enough removed from my teenage years that I don’t remember the full range of complex emotions that go along with adolescence. I’ve read a good bit about how to (and not to) approach writing from the point of view of a teenager and/or for a young adult audience. This article has some good tips to consider.
Fortunately for me (most days) my job has me surrounded by young adults of all varieties. I get to hear about what matters to them, watch how they act, and talk to them. I get to see how they respond to learning new/interesting/funny things, and I get to see how they react to discipline, disappointment, and getting hurt. There is no shortage of the adolescent voice in my world, and that helps me write. I’ve told a large handful of my students about the plot of my current WIP and it’s been nice hearing their feedback…especially in the earlier stages. I a had few ideas that more the one student shot down as weird/lame/uninteresting. I did keep a few of those reject ideas anyway because I know they’ll fit naturally in the full context of the story, even though they apparently sounded strange when isolated. Either way, I appreciate the access I have to people at least somewhat like the characters in my story.
