life has its ups and downs. if u have ups you would have downs. It goes like a normal phenomenon. The more the light shines upon you the more the shadow gets darker. The world has its own nature. And having the darkest night means you know there was once a brighter day.
Yeah i agree with the quote. i think this quote means that even if today was hard, tomorrow will be better. it also means to always have hope. hope helps make a tough present situation more bearable but also can eventually improve our lives because envisioning a better future motivates you to take the steps to make it happen.
