If you want to appeal to a broad audience I'd say tone down the "debating complex intellectual questions" stuff. most teenagers aren't terribly intellectual but this kind of advice is important to them and you want them to be imagining themselves in your shoes.

Personally I was very lucky, my parents didn't pressure me into a particular profession though I have ended up in a somewhat similar area to my dad.

I did initially consider studying physics or math in college and missed getting into physics by just a few points but it was very much for the best as I realized later that the things that had appealed to me were much more in line with CS, I thrived in CS where I would have merely done OK in physics or math.

Of course, if anything I do it too much, I spent about half my life perpetually living for 5 years in the future. Sometimes it's important to stop planning and enjoy the current time.

On the note of career choices, I quite like this old quote of EY's:

"Have I ever remarked on how completely ridiculous it is to ask high school students to decide what they want to do with the rest of their lives and give them nearly no support in doing so? Support like, say, spending a day apiece watching twenty different jobs and then another week at their top three choices, with salary charts and projections and probabilities of graduating that subject given their test scores? The more so considering this is a central allocation question for the entire economy? "
