For most people, learning how to water ski on two skis is pretty easy, but learning how to single ski is quite difficult. A recommended way to work toward learning how to single ski is to start on two skis, and then learn how to drop a ski. Once you are comfortable dropping a ski, you can then try starting from a single ski, which may take many weeks to learn, as well as require a fair amount of strength and athleticism.<|im_end|>
