I think I learned to swim the easy way, after several tries with swim class at the city pool that gave me a chance to size up the problem and consider how I might get it done myself. I ended up with my family on vacation at a resort with a lakefront and swimming area with smooth pebbles rather than sand under foot. Rather than proceeding from shoulder deep water, I got a little over waste deep, pulled on a diving mask to avoid water-in-the-eyes, and plunked down on my belly. Unavoidably, I floated, and after that, all I needed was to pull with my arms and kick with my legs and feet. No fearful plunge. I felt like I had cheated terribly, but by that afternoon, I was swimming in water over my head. If you have a kid or grandkid who is not taking to the water with comfort, this might be the way. I know many resort to the old rite of passage of throwing the kid in the deep end, but I recommend the easy way, because it gives the new swimmer a sense of control. The water floats you. Carry on.
