To fail inspite of having tried really hard is sometimes essential.

Okay, so it's mostly essential. For someday when success sweetens the toil, it'll be because of the hardship that was overcome along the way. When knowing that though giving up is easy, it is also never really an option; when we, without regret undertake long hours of work to do what must be done, and would do it again. And again. Even though the oasis turns out to be another mirage, to taste the waters of success someday, one must undertake those long roads, impassable gorges, hobbling, stumbling, and yes keep hope burning within. While toil is necessary is not sufficient to guarantee success in the eyes of the world. But definitely in ones' own.
