Apparently, Shakespeare is not essential for getting rich...
It might even hurt a VC professionally. E.g., I can understand that a VC would not regard "Neither a borrower not a lender be" a serious or useful advice.
And I have lost count of the occasions when I had to quote
We work by wit, and not by witchcraft,
And wit depends on dilatory time.
to various VCs and managers.
Admittedly, having read all of Shakespeare and being able to quote some stuff from memory did not make me rich. Not in a sense a typical VC could relate to, anyway.
[Aside: both quotes are by not the most attractive of Shakespeare's characters, but not the stupidest, either. A VC would probably point out that both were ultimately unsuccessful.]
