I think this song is about how teenagers all think being grown up will be so much better but in reality we need to make every day count cause it'll be over in the blink of an eye. And the ironic thing is that he's singing about how we only have 100 years. most people don't get 100 years even, so 15 is just the beginning and we need to appreciate every day. don't focus on how messed up your life is. live it and make it count.
