I took kung-fu for 8 years, and helped teach for three of them while I was younger, does that qualify me as experienced?
Basically, the most important thing you need to concentrate on at first is your breathing, and relaxation in general. Get comfortable, but make sure your back is straight. Take deep breaths, in through your nose, out through your mouth. Put your tongue on the roof of your mouth, lightly pressed behind your two front teeth (I was taught that this aligns your bodies energy flows, chi, but years of research in my spare time has not yet found a scientific basis for chi, so lets just say that it usually works better this way 😉). Picture a background and concentrate on this to the exclusion of everything else. Most people use a simple black background, and consider this clearing their mind of all thought, but a white background is just as effective. Continue your concentration and breathing, and you will find the utter calm. After a lot of practice you will be able to do this almost instantly, and can use it to control your temper or anxieties. Lol, you can push this farther and get almost a high from meditating (oxygen is one of the best drugs 😉), but you need to concentrate on the basics first.
