> have always been deeply interested in computers, but have nonetheless felt inexplicably out of place for it

You know what stopped me from becoming a professional programmer? It wasn't the fact that I didn't get to study CS in high-school, nor that I didn't have a PC until I was a university student, nor the lack of Internet access at home until I was 20+ years old, nor the language barrier (English is my third language), nor being limited to free resources by my finances.

Nothing. Nothing stopped me from pursuing my interest.
