One loop of Renaissance Man rekindled my passion for languages — Japanese exercises were significantly better than usual

I ran one loop of RM today. It's rekindled my passion for foreign languages even though I told my gf a couple of days ago that I lost it completely. I did a Japanese learning session one hour after running that loop and my results — guesses and grammar and vocab exercises — were significantly better than usual. I'm confident there's the Polyglot module in RM. On top of that, my verbal fluency has improved a bit.
