From Mark Twain's The Innocents Abroad: Or the New Pilgrims' Progrss:Substitute the words "Europe" and "Jerusalem" for "life" and this will inspire you...
"We are at home again. We are exhausted. The sun has roasted us, almost. We have full comfort in one reflection, however. Our experiences in Europe have taught us that in time this fatigue will be forgotten; the heat will be forgotten; the thirst, the tiresome volubility of the guide, the persecutions of the beggars--and then, all that will be left will be pleasant memories of Jerusalem, memories we shall call up with always increasing interest as the years go by, memories which some day will become all beautiful when the last annoyance that encumbers them shall have faded out of our minds never again to return. School-boy days are no happier than the days of after life, but we look back upon them regretfully because we have forgotten our punishments at school, and how we grieved when our marbles were lost and our kites destroyed--because we have forgotten all the sorrows and privations of that canonized epoch and remember only its orchard robberies, its wooden sword pageants and its fishing holidays. We are satisfied. We can wait. Our reward will come. To us, Jerusalem and to-day's experiences will be an enchanted memory a year hence--memory which money could not buy from us."
Time does pass and life's difficulties, one by one, fade from remembrance. In the midst of trials, try to remember that soon your pain will be less than a memory. In fact, you won't remember it at all.
