I really need to pay attention to my sleep. My ability to do anything goes down severely when I don't sleep enough (which for me is less than 8 hours a day). So much so that it's enough of a reason to not have kids (I suspect I'd lose my job and/or go crazy), at least not until I'm financially independent. Apart from that, it's mostly all in your head - i.e. at least in my case, motivation/demotivation largely depends on whether my internal self believes that the effort is actually worth it. So, for eample if the project is actually pointless (will likely not deliver value to anyone on completion), I will be demotivated. Also, if my effort is unrecognized, this will be demotivating as well. Having to deal with completely preventable bullshit every day (general corporate incompetence spilling over my particular area of work) is also demotivating.
