on monday night i was watching a tv show that i like, its name is what about brian.
there was this married couple having an argument
at the end the husband said something like, when things were going wrong with his wife all he had to do was picture himself without her and there he found the strength to keep the relationship going
it was pretty sweet
personally, i think you it applies for the everyday routine that at certain times make us feel tired.
you just have to ask yourself: if there's something else i'd rather be doing?
if the answer is yes, maybe you just need a change and it is up to you to make it happen
if the answer is no, the keep it going
