I like eating and sleeping. I pay a lot of attention to these things. If you're eating well and sleeping well, your life is probably going pretty good. Sure, I'm going to die, that's why food and sleep matter even more. This planet would be a pretty happy place if everyone was eating and sleeping as much as they needed.
Second, what the heck. Too lazy to work on perfecting myself? I thought spiritual enlightenment was about having a smaller ego, not a bigger one. I'm going to feel more motivated if I focus on how awesome I'll be if I do the inner work? You can't do this stuff for very long because you want to get something out of it, you only do it in the long term because circumstances push you into it and you have no choice.
Third, details vs. essentials. Details are bad now? You won't get far with only one or the other. Yes, essentials are important, but so are details. In startup terms, a great idea is essential, but you're dead without a great execution.
Anyway, "laziness" is such a crap word in a spiritual context. As if enlightenment was an achievement, when the point of just about every religion is being, not doing.
Eat. Sleep. Give yourself a break when you hit a wall; perhaps you ought to re-evaluate your priorities. Do a thorough and meticulous job on all of your little projects. Pay attention to what you're doing, and you'll come out of it all the wiser. Lack of progress in any one area is not laziness, it's a signal that you need to try a different course of action.
