Days of dullness and bleak boredom come in midst of days so happening, one has not but one second to spare. It is the way of life, in between the exuberant highs and the depressing lows lie the moderate days of boring normalcy. Normalcy to a few is better than struggling between somewhat of a bipolar situation of joyousness and melancholy and to a few is restlessness for the occurrence of something that would make them feel something extreme yet again.
We are all different and have varying degrees of highs and lows, but none from the human race is such that hasn't experienced a period of having absolutely nothing to attend to or perhaps it is more of not wanting to follow out a routine of daily menial chores, usually it is the latter that's true. It is human tendency to look out for a new adventure every once in a while, no doubt a few days of boredom here and there are well appreciated for the much needed relaxation of the ever functioning brain.
All in all despite being from the same species and being inhabitants of the same society, we all have a different definition for a happening day - to some it is tiring and hectic, to others it is yet another adventure, something new, what matters is you appreciate that you are still alive, still breathing and have a spectrum of days awaiting your presence, at least that's what each one of us plans out life around, but you never really know if there will be a 'next' day, so be it a day of a high, a low or monotonous mediocrity. Live it to its fullest potential and rejoice in every moment, each one of them is a boon.
