Can't say I disagree with this. The amount of time I've spent worrying about writing the perfect story is ridiculous, and that perfectionism has been a reason I've missed quite a few trends I probably should have written articles about.

That said, you know what makes this even worse?

Having a SEO plugin installed. Having the software yell at you about 'readability scores' and 'transition words' and not using the same word at the start of three sentences in a row will make you even more obsessively picky about your writing than merely being a perfectionist will.
