Remember that there is a difference between toxic topics that should be avoided entirely, and ‘go carefully’ topics that are perfectly fine but easy to do badly (the ‘Zzzzzz’ topics that @PrimeMeridian lists).
Don’t fret too much about getting an entirely unique topic. There are a limited number of topic-worthy life experiences that you can accumulate in 17 or 18 years. Colleges know that. Avoid the toxic topics but beyond that focus on avoiding cliches inside your essay.
To take one of PrimeMeridian’s examples: Thousands of kids successfully use their sports experiences as essay topics every year. They do so by writing about their genuine passion for their sport or about how their sport shaped their life in some important way. Kicking the ball into the goal doesn’t tell the admissions committee what kind of person you are off the field.
