Just because you get a fancy camera or a sketchpad, or organized one party using pinterest doesn’t make you a professional. Just because you did or got any of that doesn’t mean that you can just start a company and magically make money.
Unless you’re some crazy prodagy or something that’s not how it works. You start at the bottom and work your way up, not because they want to make you feel bad but because that is how you learn. There’s a reason most successes are those who are older.
This also relates to college degrees. Just because you graduate in college doesn’t mean you’ll automatically be a CEO. College just makes you better prepared for a job, it doesn’t magically give you one.
