The market always has endless hot trends to chase—one moment it's gold, silver, non-ferrous metals, and oil, the next it's storage, electricity, and aerospace. You finish cutting losses in one area only to start in another. I often remind myself: keep your mind steady and, more importantly, control your hands! If you don't understand something, it's better not to touch it. Otherwise, the money you made will eventually be lost the same way you earned it!
