Respect your soul: don't keep repeating "I'm going to make it". Your soul already knows that, what it needs is to use the long journey to be able to grow, stretch along the horizon, touch the sky. An obsession does not help you at all to reach your objective, and even ends up taking the pleasure out of the climb. But pay attention: also, don't keep saying "it's harder than I thought", because that will make you lose your inner strength.
