@mmarco You're a prime example of you don't know what you don't know.
You're being a bit black and white in your post. Education is important and should be encouraged. Asking you to pay attention when you're in a place where you're supposed to pay attention is not unreasonable. You were being really disrespectful to someone else's time and effort tbh. If I was building a side hustle at a corporate job blatantly in front of my boss, I'd expect a similar remark.
Also, you're looking at success very linearly. Just because you made 40k doing this does not mean you can guarantee that going forward. Being well educated is a great safety plan, adds credibility to future ventures, provides opportunities to network, great foundational skills and exposure to other points of view.
I come from a family of entrepreneurs and we've always stressed education for the reasons listed above. Don't knock it just because you decided on a different path, that's being narrow-minded.
I understand you mean to encourage entrepreneurial teens BUT acknowledge you haven't lived a long time and have no idea how much easier life is when you have a good education in case a business fails.
Your message would seem more mature if it was "you're never too young to start a business" or "entrepreneurial skills are a great addition to lessons learned in school" vs "fck the teachers, piss on education and let's chase dreams."...
Congrats on your early success.
