I recently read a talk given by Elder Jeffrey R. Holland, called "However Long and Hard the Road" .
What a powerful testimony of diligent hope and perserverence.
This was my favorite excerpt from the talk. Read it. I promise it will guide you.
"As you wage such personal wars, obviously part of the strength to "hang in there" comes from some glimpse, however faint and fleeting, of what the victory can be. It is as true now as when Solomon said it that "where there is no vision, the people perish" (Proverbs 29:18). If your eyes are always on your shoelaces, if all you can see is this class or that test, this date or that roommate, this disappointment or that dilemma, then it really is quite easy to throw in the towel and stop the fight. But what if it is the fight of your life? Or more precisely if it is the fight for your life, your eternal life at that? What if beyond this class or that test, this date or that roommate, this disappointment or that dilemma, you really can see and can hope for all the best and right things that God has to offer? Oh, it may be blurred a bit by the perspiration running into your eyes, and in a really difficult fight one of the eyes might even be closing a bit, but faintly, dimly, and ever so far away you can see the object of it all. And you say it is worth it, you do want it, you will fight on. Like Coriantumr, you will lean upon your sword to rest a while, then rise to fight again"
