What no one else has said here:
Whatever her past experience, going to Yale (bring it Yale redditors... are there any?), her solo practitioner work (maybe she did grind it out chasing clients), or whatever else (who doesn't make the federal judiciary by age 37?)
SHE HAS A LIFE TENURED POSITION THAT, IF WE ACCEPT THE ABA 2010 NUMBERS (1,225,452 LAWYERS AND 9 SUPREME COURT JUSTICES), REPRESENTS 0.00073% OF THE LEGAL PROFESSION.
Her advice comes from the position of someone with complete surety.
