The only job I've ever succeeded at was in a quiet, orderly lab, with statistics to work on, and with a place always available where I could go to be alone in case of meltdown. Ironically, I never used it--it was just the fact that it was available that helped enough that I never actually needed it!
Other jobs, eventually I would just get so disorganized that I wasn't taking care of myself properly; eventually, I'd simply be too tired, sick, achy, and generally out of sorts to be able to drag myself out of bed and to work. Usually within the first week I'd have to give up everything but working and recovering from work--no free time, no hobbies, no nothing. And that included weekends. The eventual burnout, after a couple of months, was unsurprising.
