&gt; Please don&#x27;t assume that because something is easy for you that it must therefore be easy for everyone<p>But I didn&#x27;t say changing my sleep cycle has been easy, and I didn&#x27;t even say I&#x27;ve managed to do it by my selves. Or that I even would have healthy sleep habits at this moment. But depending on mental health, diet, exercise, employment vs studies. These things have made me have all sorts of sleeping habits, and my personal belief is that these outer circumstances has had much greater impact on my sleep then anything in my genes. And that&#x27;s why don&#x27;t like this idea of morning and night persons as it only enhances thee feeling that you can not change your ways.
