I suppose if working makes you happy then I can't argue with you. But for me personally, working does not make me happy. I could have worked over the summer in order to get good grades, in order to go to a good uni, in order to get a good job and perhaps I would have achieved all that. But at the end of the day, when I looked back on it all, what would I have achieved? None of that, would have made me happy. Being happy in each moment, instead of constantly working towards some goal in the future is what makes me happy. And to that end, having a stress and work free holiday enables me to have a truly happy and fulfilling life.
