I'm roughly your age, and started programming around 10, doing my first paid work around 18 on a part-time-while-studying basis. I truly miss the days where one person could know a lot about a lot. Nowadays, it's a struggle to either know a reasonable amount (not even a lot) about some niche area, or even just be barely competent in a wider spectrum of things.
Where are you based? I was starting to think the problem might be limited to areas or regions (since almost everyone I know elsewhere seems so content/fulfilled).
