There's people that like comfort, that don't want to change what's good, that leave things just like they are because it doesn't need to be changed, and there are those that like adventure, the uncertainty, the new stuff, opportunities, adventure in itself. Each of these have advantages and disadvantages, depending even more on the type of person and his/her mentality. And if we really are one of those two types, maybe we need a little bit of the other type, whether to calm your own spirits, or to wake them up.
I created this thinking of those two types and assigning them to day (adventure) and night (comfort), and I made the main setting at night because that's what I'm used to see from a lot of people that I know and care. And that's just fine, comfort isn't a bad thing as some people think, it is as good as adventure is for adventurous people. I am a bit of both, I like to have comfort in my life for shorts amounts of time, but on the long run, I need that "door" to adventure, to keep going and advancing onto new projects and trying to evolve, because that's what makes me feel alive.
