Sorry, meditation is not a quick cure-all. You will start seeing changes right away, but really profound effects are years down the line. That is just the way the universe is constructed. Nothing worthwhile is achieved overnight. Meditation is tough in some respects, requiring a long discipline and a sometimes painful process of practice. At each sitting you gain some results, but they are often very subtle. They occur deep within the mind, and only manifest much later. And if you are sitting there constantly looking for huge, instantaneous changes, you will miss the subtle shifts altogether. You will get discouraged, give up, and swear that no such changes could ever occur. Patience is the key. Patience. If you learn nothing else from meditation, you will learn patience. Patience is essential for any profound change.
