whats the book/short story where the guy agrees to get locked in a room for like 10 years in order to get 1million dollars

something like that, i had another one but can't for the life of me remember

yes I remember reading this.

He makes a bet that he can stay locked in a room for a million dollars for 10 years.

Then, on the day before the 10 years is up, he leaves and left a note on a table.

I'm sorry but I can't remember the title, it was a cool short story though.

yeah it was, there is one more that is better and i can't remember any of it for shit.

anyone else know the actually name?

I know about this:
