I've often felt the same way. So much so that I even did some testing a few years back to see if I might have undiagnosed attention deficit issues (turns out I don't). The worst byproduct of this is that it brings some shame with it. I've never had jobs that demanded all that much of me - I worked some intense hours when freelancing, but for the most part I've had very flexible jobs with good work environments. My wife works insane hours as a tax accountant, and although it makes her miserable a lot of the time, she always seems to be able to power through her 10-14 hour days during busy season. I feel myself mentally checking out after just 4-6 hours some days. It's embarrassing that I don't seem to have the same work ethic as her (and many others). I've tried productivity tools (pomodoro-ish stuff mainly), but they never seem to quite fit in with the kind of work I'm doing or with the work environment at my job. I'm looking forward to reading through this thread to see if there are any recommendations I can take from here.
