I have a 3.9 GPA at a competitive high school. I have taken more APs than my school technically allows. I have a solid SAT score that isn’t AMAZING, but it’s in the range for most top schools.
I am president of 3 clubs at my school. One of them is the social justice club, one is a language club, and the last is the largest club on campus that gives tours to prospective students. I was elected to these positions. I do Model UN and have won 3 awards including best delegate. I am in my school’s honors drama society and have done the musical and play every year. I am also a peer tutor in humanities courses. I am a peer mentor and am on the disciplinary committee. I also did a homestay in another country as part of the language I take. I also attended a highly selective summer program in my field of study. I am on my school newspaper and write regularly. I also won a high selective competition to be published in the New York Times. I was in the top 12 of 10,500 contestants. Finally, I run a political instagram with over 100,000 followers.
how can i develop my spike and narrative when I apply?
They are nice accomplishments but none of them are a hook.
You don’ want to be labeled “spikey.” You want the right rounding. And since you haven’t mentioned target colleges or major, we can’t offer much feedback.
If this is for a top college, tey aren’t looking for number of social media followers or titles in this club and that. They want to see some stretch, not just hs focused.

You have amazing accomplisments, but none of them stand out. What I mean is that you didn’t pursue any of them to the best of your ability.
You don’t have a spike. You probably won’t have one by the time you graduate.
What you do have is a nice, well-rounded collection of ECs. I’m not getting any sense of which one or two of those is/are most important to you. Being president of three clubs shows you are popular, but without knowing more about what exactly you do in those positions and for those clubs and their members, it is impossible to say whether the titles, in and of themselves, show real leadership.
One challenge for you is to find the common thread among those activities. What motivates you to do them? Why those activities over others? If you can thread them together, you’ll have an easier time showing the colleges who you really are, what you can offer them, and why they should want you on their campus. That’s what it is really all about (not whether or not you have a spike).
Since when winning a big competition and being published in the NYT as a HS student is just “nice”? Nothing short of a Pulitzer is impressive anymore? 
Whatever you call it - a spike? a direction? - your journalistic accomplishments, in the old media and in the new, stand out.
