Caught by the torrent of life

I've been wondering for some time if there was any possibility to automate MS Excel's button-bar function, GoalSeek.
Recently, I tripped over this answer on Excel Workbook, which looks simple and effective.

It's not long since I joined one of the best book-readers social site (and not only), GoodReads. Some of the reasons for which I joined the GoodReads community were getting to have a visual representation of how many books I read, exchanging book impressions with other felow readers, keeping in touch with news about books being published around the world and, later, when I became a GoodReads Librarian, keeping the world informed about books from Romanian Authors.

Recently, GoodReads has conducted a poll about favourite books of 2011 and some days ago the voting has brought us the winners.
