It's a strange feeling to have long planks attached to your feet. Beginners want to see what the tips of their skis are doing at all times and often make the mistake of not looking forward. This has the same effect of looking down at your feet when you're walking around -- you're bound to run into something. Ski instructors suggest looking about ten feet (at least) ahead of you at all times. You can prepare for uneven terrain better, have a better sense of where you're going, and focus more on what's next, not what's now. Besides, it helps to see that tree up ahead, especially if you are moving faster than a snail.
Editor's Hint: Looking ahead of you will automatically force your body to move that direction. It's just like throwing a ball- where you point you're hand is where you'll go.
