Quote/Essay help

[Thunderstorm]

Not sure if this is quite the right section for this but I'll post it here anyways. I have to write an AP argument essay on the accuracy of the following quote in modern time:
"Most men go fishing without knowing that it is not fish they are after."
-Henry David Thoreau
I can use any examples to support this and I have one but I need another. I already know the meaning of the quote. What example supports this quote? If you don't know, I interpreted the meaning of this quote to be that most people do not know their true calling in life even if they pursue a certain path.

It could also refer to the pressure society puts on us, by making us "go fishing", even if that's not what we want to do, that's not what we're good us. Sort of making everyone a fisherman, though some need to be hunters or smth.
