There's the old adage, "jack of all trades, master of none," and it exists for a reason. As someone who is interested in a lot of things and loves to absorb all sorts of information, it has had the unfortunate side-effect of lagging behind in my actual education and career for many years. Of course, I'm generally not a super smart dude and that probably contributes but I've just never been one of those people who could sink their whole being into one field and am like the fox who chases two rabbits but gets none.
This is true because it is a matter of survival in our civilization (i.e. division of labor). You can easily see the people around you who just ride smoothly by in life because from even before the time they left school, they knew what they were going to do, and when they went to university/college they invested themselves only in the particular field when it came to reading about anything. Their lives become effectively defined by their job and when they're not working, very often they'll desire "going out to drink with friends" or "netflix and chill" or something of that nature. It's how you get by well in these days, though.
