i know they're her private journals, and shouldn't necessarily be used as a rule book of any sort to live by; but being 19 myself, i thought i could gain knowledge from a girl who i assumed would most definitely have more common sense than i do.
i'm almost 200 pages in and am actually growing quickly tired of trying to track the different dates and men and boys. maybe the absence of her father plays a big part in this, but whatever enchantment sylvia has worked up in me is quickly made dull by the beginning of her next entry, which is a complete 180 from the last, in the span of a day (i love him, never mind i hate him, and there's this other guy).
one day she's accepted in mademoiselle, eating caviar, drinking champagne staying out late and the next (for no apparent reason) she's dejected, hopeless. and she says it herself, she has everything and more. and i'm unfortunately not seeing it as "no matter how much you have you're still empty", rather than as "this girl has absolutely zero foresight".
these journals have served only to paint sylvia as an extremely ungrateful person, and unfortunately i've gained no insight or found any knowledge to superimpose onto my own life (other than observe how childish and unappreciative one of your favorite authors realistically is)
I guess I'm confused why you thought a nineteen-year-old who eventually kills herself due to her perceived hopelessness would have more common sense than you. Sylvia Plath, for all the gripping art she constructed, is one of the last people I would turn to for common sense.
