I have been working on a large side project which is no longer just a side project. I am not getting as many hours of work in as I would like, but at the same time I know if I tried to do more, I wouldn't be productive. In fact I'd do negative work. Years ago I would push through and work anyway (I am a real goal oriented person.) Knowing what I do know now, all I can do is shrug my shoulders. It's like distance running - for all the desire to work harder and do better, speeding up won't get you to the finish line faster. If you have some sense of your limitations, you no longer can really feel guilty about being lazy for this. It may be worse though, because then you can feel bad about your capability. Hopefully that is something you can just accept.
