- focused: Executron Personal Stock Ticker, Executron Desk Pen Set
- confident: Chronos Magazine (Framed Collector's Edition Issue)
Add info that Research Stocks adds 4h +1 moodlet on completion, it's very slow though.
Would be nice to have an idea of how much time, relative to each other, actions take to get the moodlet. For example, you don't need to keep playing chess to get its +2 focused moodlet (but your sim will keep playing), so you can cancel it; researching stocks takes forever, while staring at emotional object is almost instant.
Also just talking can give you all sorts of emotions, some of talking options unlocked in business career give +2 focused, for example.
