Weary and Exhausted

"Even youths shall faint and be weary, and young men shall fall exhausted; but they who wait for the LORD shall renew their strength, they shall mount up with wings like eagles, they shall run and not be weary, they shall walk and not faint."
Is 40:30-31

Ok, so maybe I'm taking this slightly out of context but I found this passage from today's first reading rather encouraging. . . I will make it through these last few days of exams, even though I'm tired and exhausted. Up next. . . metaphysics! Yikes!
