My MSc thesis on experience of emotion in natural environments. I interviewed 18 people to discuss every possible aspect of experiences they've had in nature. 
So now I have chapters with stuff that influences the experience of emotion. Like weather. Other people. Associating a situation (a dead forest) with something else (the apocalypse). How wild the area is. How well people know it. 
I like it, but I lack some self-discipline and motivation. 

 Getting better though.
