All Zach Sobiech wanted to do was to say goodbye to his family and friends.
In the process of doing that, the 17-year-old has inspired, exhilarated, touched and entertained hundreds of thousands of people, moving some of them to tears and motivating others to change their lives.
Told that a rare form of bone cancer has likely left him with only a few months to live, the Stillwater High School senior wrote a song titled "Clouds" in which he bids farewell to the people around him. "Maybe someday I'll see you again," he sings. "We'll fly up in the clouds and we'll never see the end."
The song, begun as a basic recording on his cellphone, has worked its way up to a professional studio version that has been accessed by more than a million YouTube users and is available for download on iTunes. The song's success mystifies its creator.
"I don't know why so many people care about it," he said. "I know why it's special to me, but I didn't think it would be special to others."
Sobiech, who lives in Lakeland, has been flooded with requests for media interviews. Stories about him have appeared everywhere from Billboard magazine to the United Arab Emirates Press. A week ago, a CNN camera crew followed him around school.
"It's been pretty crazy," he said.
The crazy part, many would say, is that being an overnight sensation hasn't had any effect on him -- beyond the fact that he sometimes notices "more girls smiling at me."
