Notice that when the mind is quiet, often the first thing you feel is anxiousness, restlessness. Notice the urge to constantly be doing something. This is why meditation is so difficult for people. You meditate because you want to relax but instead the opposite occurs! Instead of feeling peace, you become frustrated, and I wonder how many people quickly abandon meditation because of this?
You may feel you're doing something wrong because you feel anxiety when you were expecting peace, or you believe you're simply unable to still your mind. However, this isn't the case at all, and the fact that you're feeling this restlessness, this constant desire to be doing something, is the first step to overcoming it.
One may be led to believe that the restlessness was brought about by the meditation, but it was actually there before you even started, you just weren't aware. The mind combats this feeling by staying constantly busy, always doing doing doing. The mind is constantly restless, and moments of real Peace are few and far between. Real stillness has become something foreign, and this constant anxiousness has become "normal". Of course, because it's "normal" now people are barely aware of how much stress is in their life, especially because of the way our society deals with this anxiety, through distraction.
