I think people who are BOTH those things ARE rare, as the OP says
I think there are a lot of people who are driven, but don't TRULY know what they want
It's very rare to find people who truly know what they want. A lot of the people who are driven, are just following a certain pathway. They are not actually sure that it's what they want, they are just following it to see where it leads. They usually don't realize that though
If you ask me, this species could use a little less motivation. The people who are motivated are the ones causing all the trouble. Show me some lazy prick who spends his days watching game shows and stroking his penis and I'll show you someone who isn't causing any f-ing trouble.
