Until you find something that resonates with you more or a good teacher, just try this.

* get a comfortable chair which allows you to place your feet flat on the floor comfortably
* i'd get a non-harsh-sounding alarm. if you have a palm pilot, get the program "Pocket Doan," and I'm sure there are others as well for other platforms (Google "Mindfulness clock" if you have a PC)
* sit with your back straight, feet flat on the floor, hands in your lap, and generally fairly relaxed (maybe take a deep breath or two before starting)
* for the practice, count your breaths from one to ten, then start over, and repeat until the alarm goes off
* your mind will almost surely start to wonder. If so, calmly and gently bring your mind back to the practice and start counting your breaths again. You are going no-where with this practice, and so you don't have to rush it.
* if you have trouble focusing your mind, just keep practicing, even if you don't get past one. You will get whatever benefit there is to get out of it anyway. Don't place any metrics on your practice. Just do, as a poster commented above, "right practice."
* once you are comfortable doing this, you might add music, mantras, or whatever else helps you.
