"Mir" is a word in ENGLISH

I could not sit seriously down to write a serious Romance under any other motive than to save my life, & if it were indispensable for me to keep it up & never relax into laughing at myself or other people, I am sure I should be hung before I had finished the first chapter. No - I must keep my own style & go on in my own way; and though I may never succeed again in that, I am convinced that I should totally fail in any other.
