I was recently walking on the Cornish Coastal Path; it's a beautiful, windswept trail with plenty of challenging climbs and descents. On one particularly steep ascent, I remembered a tip I read many moons ago in a mountain biking magazine.
The tip was about tackling long arduous climbs: it described how if you only focus on the top, your mind will begin to doubt that you can get there, and you are more likely to fail. However, if you look just a few yards ahead, far enough to avoid any obstacles, you will grind out the climb almost without fail.
The trick is to focus on the task ahead, only occasionally glancing up to make sure that you are on track to achieve your ultimate goal. I applied this trick and tackled every climb comfortably.
The experience brought to mind how setting short-term goals can be the perfect way to crush longer-term targets, and this is why.
