I am ever so mildly OCD especially if I am bored so it definitely helps me to avoid constantly checking something that is changing (sometimes dramatically) frequently.

I day traded for a year between when I left my corporate job and really focused on my business full time and I did ok but I hated it because I was constantly checking prices. I would wake up in the middle of the night and be compelled to see what overseas markets were doing. Was a terrible lifestyle, at least for me.
