The steeper and more difficult the climb becomes, the closer you are to the summit. The more you feel like quitting, the more there is to be gained by continuing to persist.
When it seems you cannot go on any more, that means you're getting closer and closer. Find a way to keep going and soon you'll make it all the way there. With every difficulty that arises, the eventual accomplishment becomes that much more fulfilling. The more effort and sacrifice that's demanded of you, the more value you are creating.
What a shame it would be to turn back when the goal is almost within sight. For the sake of all your previous efforts, keep going and make those efforts count for something truly great.
Every bit of weariness you feel is proof that you've already made much progress. What a blessing it is that you have what it takes to keep moving steadily forward.
Keep going, especially now, for just over the next horizon is where you were meant to be.
