It sounds like you have a book addiction, Tons XD
I always try to collect one of each book and put them in shelves in an organized fashion. I actually save every scrap of paper and journal I come across or am given, including the lame assassin notes. I saw a mod that lets you put them into a book, and I think I need that...
And gems. I don't sell them, I drop them in a basket on my table. It take so long, but looks so rewarding...
I too take the watery route down from Dragonsreach and jump the stairs leaving the city, Also, my method of leaving the Throat of the World: Become Ethereal and leap, and hope it lasts long enough. I'm too impatient to go down mountains the right way.
I also never wear armor, ever. Cloth and jewelry, cloth and jewelry.
And if I see a Vigilant of Stendarr I pass them by in silence, but when they inevitably say something snarky, intolerant, or rude I let them go by, sneak up behind them, and slit their throats with Mehrunes' Razor. I woulda lived and let live, but then they had to be jerks...
Last thing: I close door behind me everywhere. It bothers me even in real life or in movie when I see people open a door and leave it that way, in my Skyrim I can take control of that. ^^
