^ I don't know whether it'll be the best advice for you or not, because people have different goals when they meditate. Some have an almost fixed need to have less thoughts running through their mind while they meditate, while others seek deep thought, and others just let the thought pass through as if it were a bird flying past their window - there, but not consciously directed.
I'm of the latter group, and the way I meditate is to find a nice spot somewhere I can sit down, ideally somewhere well lit, that smells and looks nice, often outside or by a window with a nice view of the mountains near my house. I sit down, often cross-legged, but with no particular stress or strain in posture, just very much relaxed, with emphasis on being comfortable so I don't feel any need to fidget or adjust my position constantly. Even sitting with your legs outstretched like a toddlers, or sitting on a couch, or laying back in bed are perfectly fine postures for meditation, provided you're comfortable and able to relax.
Once I'm sitting there, I let my gaze fall just in front of me, between 1-3 feet directly in front of my (usually crossed) legs. I find a general point to look in the direction of, but I do not stare or focus my vision on it, nor do I turn my head looking around everywhere. I just keep my head mostly still, looking vaguely at the point in front of me, observing what goes on around the point, whether it's a shadow moving across the floor, or an ant crawling, or the tail of one of my dogs wagging.
If I need to scratch my nose, adjust my position, or even move my head ever so slightly, I do, since if you constrain your movement it just causes stress and reduces what you achieve. As you attend to any such desires to move slightly, you quickly become more relaxed and soon you no longer need to move or scratch, and you'll find yourself perfectly relaxed in your position.
As you look in front of you, your senses gradually begin to heighten, and while you initially could just see a small fixed area around where your eyes were pointing, you start to see all the detail around this area, hairs on the floor being brushed aside by the breeze coming in the window, flickering of the light a butterfly dances around past your window, the dulling of the sun as a cloud passes across it. Your hearing also becomes more sensitive, and you start to hear the smallest sounds, the most distant chirps of birds, the deep breathing of your sleeping pet, the rustling of the leaves outdoors in the wind.
Now you're meditating perfectly, and you're a passive observer with senses tenfold those you have most of the rest of the time, when you aren't really *truly* seeing or listening like you are in this moment. Observe and be a part of this tranquil scene, and enjoy the beauty of what unfolds before you, and the rapture you experience as joy, delight, and wonder fill you up.
Meditation is a really beautiful thing, and it took me a long time to grasp, for the longest time I just did the whole: "Cross my legs and close my eyes and try not to think" thing - when I learnt observational meditation like I practice now it was like night and day, the states of extreme happiness it can bring on, and the wonderful things you can hear, see, smell, taste, and even occasionally touch during such an experience are astonishing.
