"You know, I spend most of my life turning things down. There's a lot of crap out there"

Bea Arthur's quote talks to the idea that there is a lot of "crap" on the planet, and that it is necessary to be selective in what one chooses to accept and engage with. This is especially real in the show business, where Arthur invested much of her life. She likely had to deny lots of offers and jobs that she felt were not up to her standards or that she did not believe in. This quote is a reminder that it is necessary to be discerning and to not opt for anything less than what one believes in. It is also a reminder that there is a great deal of "crap" out there, and it is necessary to be familiar with it and to not get captured up in it. Arthur's quote is a tip to be mindful of what one picks to accept and engage with, and to not hesitate to turn down offers that do not meet one's standards.
