In my experience, it's actually very hard to do so. It takes active practice to reinforce a way of thinking that's just not natural. You can check out "The Power of Now" by Eckhart Tolle for suggestions and techniques to quieting your mind. I believe one example for those just starting out is to observe your inner monologues as they happen and simply note them. It has an interesting side effect of stopping your wandering thoughts in it's tracks sometimes. For about 5-6 months I was able to practice "being in the now" and I have to say it really was worth doing and I wish I was better able to stay in that frame of mind for longer. Alas, with most things if you don't practice it then you generally lose it.
