When I was that age, the idea of getting a part-time job beyond babysitting was insane -- not because I was so rich that I didn't need a job (in fact, I was so poor that there was a tiny network of people paying for my extracurricular activities out of the kindness of their hearts), but because I was so busy competing in speech tournaments and performing in plays and going to church to even consider a disruption to my self-imposed activities schedule. And at the end of high school, I ended up with a closet full of trophies and enough scholarships to pay for ... uh ... part of one college textbook. Putting hours into speech club was not a smart financial decision.
Actually, scratch that. Learning how to debate, speak publicly, and defend my ideas is why I have this job, and probably why the Parkland kids are holding their own in public engagements as I write this. (YOUTHS, take debate or drama if the opportunity arises!) The point is, high school is the very last time most of us are allowed to go all-in with our passions without having to worry about keeping the lights on or keeping baby humans alive.
As an adult, you have fight against everything from actual hunger to stone-cold apathy to maintain the discipline and passion that you gain in high school. I voluntarily signed up for a zero hour class my senior year, which was the exact last time I committed to being ANYWHERE at 7 a.m. in my life. As a parent, I see the track kids out running in shorts in February (in Idaho), the drama kids putting in 12-hour days to keep up with their grades while rehearsing for plays, the 4H kids doing their thing with ... feeding and then selling farm animals, I guess? Ag kids are a mystery to me.
The second you grow up, the pressures of adulthood immediately begin to steal hours away from your passions. Every high school classroom is filled with people who are actually at the top of their art game or can sing notes that they'll never be able to hit again or are running their fastest mile, and they don't know it yet. Also, every high school classroom is filled with a few kids who can talk, write, draw, act, sing and think circles around many adults in their lives, not in spite of being teenagers but because they're teenagers.
