I typically transition right from one to the other, but all of my obsessions/special interests are relatively embedded within my internal world. I might switch from one to the other, but I never completely reject any of them. I usually put one aside while I focus on another, and I may return to the one I formerly had put aside. New obsessions/special interests may come, but none will ever leave me completely. I still have the same special interest (video-games) since I was 6 years old, but I don't play video-games as much anymore since I am in college and have more important things to worry about. However, I will not ever give up liking video-games or dissociating myself from them. Another instance is my physics obsession. When I was a junior in high school I took a physics course and became obsessed with physics. After that school year new obsessions and special interests arrived, and I focused on them and put physics aside. Then came freshman year of college and my physics obsession returned, albeit enough to cause me to do a physics minor in college.
