Great article, I feel like way more people need to be saying "I don't know." People appreciate honesty. I learn something new everyday. A lot of people call it "impostor syndrome" which has such a bad connotation, I prefer to call it the "Google / Stack Overflow Developer." You have a great concept of where to start, but theres a lot of stuff you don't know. And for that, there is Google & SO.
My coding beginning was actually when I started a business picking up dog poop (no joke) when I was 9 years old to buy an N64. I convinced my dad that I needed a website if I was going to be a "real" business, and he taught me my first HTML.
