The prospect of the next day allows us not only to escape from today and its unsolved problems (After all, tomorrow is another day, realizes Scarlett O’ Hara by the end of Gone With The Wind), but to anticipate actions to be done in order to increase our efficiency and decrease stress. Furthermore, the integration of days to come in longer term projects allows us to build the future by giving it a sense. Finally, it is more productive to be keen on the hazards of existence, rather to be afraid of them, which changes nothing to it.
