I found its best to not be overly obsesive as it will just cut into the already reduced lifestyle I have. As far as OCD I like to play segments of songs over and over. I can make a 3 min song last 20 mins, however I only do this alone. I am obsesive about certain stuff when I fly. (I am a pilot) Yes, thats right, a pilot, and you have no idea how much this bull**** has hampered my career as I pick and choose when I fly based on how I feel, and almost always fly with another pilot.
