Windsurfing is one of those sports that seems to appeal to some people, but not to others. I am one of the others. It looked like an exciting sport, and so I decided to learn. I soon discovered that windsurfing means dealing with one \(1\) ... after another. The first one that you \(2\) ... is how to prepare the sail. After fighting with it for half an hour, I asked my teacher to \(3\) ... me out of my difficulty. The second problem I \(4\) ... into was when I put the surfer into the water and tried to get onto it. I had tremendous \(5\) ... in keeping my balance. Every time I managed to stand up, I lost my balance and fell into the water. This happened over and over again, until I got so fed up, I went home. The next day I was ready for more. You may think I was crazy, but I really wanted to \(6\) ... the difficulties ... windsurf like everybody else. This time, I managed to stay on the board, but quickly came up \(7\) ... another problem. I could not \(8\) ... out how to hold the sail in the strong wind. In a few minutes I was back in the water, simply because I was not strong enough to hold the sail in the correct position. After a few more hours of this, I couldn't \(9\) ... the solution, and I came \(10\) ... with a better idea — I gave up for ever, and I haven't tried again since.
