Clarifying a Quote Attributed to Sylvia Plath (Wednesday's Wisdom)

I'm using this episode of Wednesday's Wisdom as an opportunity to clarify the quotation which can be seen in the text based image posted above. Evidently the quote is associated with Sylvia Plath, a poet that I've written about in here on Blogger. If you'd like tp reference my posts about her, please click here and if you'd like to read what The Poetry Foundation has written about her, please click here.

As for the quote-based image, I first saw it on someone's Facebook Page. There was no commentary, only this image. Since I'm often plagued with self doubt, I was drawn to the quotation, but something about it didn't ring true in my perception of Sylvia Plath; so I turned to Goodreads and learned that this is not the full quote, which evidently is this:

“And by the way, everything in life is writable about if you have the outgoing guts to do it, and the imagination to improvise. The worst enemy to creativity is self-doubt." 

According to Goodreads, the full quotation is from The Unabridged Journals of Sylvia Plath. She died from suicide on February 11, 1963.
