Survivorship Bias
The Fallacy
Only looking at the winners and ignoring all the people who tried the exact same thing and failed.
Why it's wrong
If you only ask people who won the lottery how to get rich, you'll forget about the millions of people who bought tickets and lost.
Example
My favorite singer dropped out of school and became rich. So if I drop out of school, I will definitely become a rich singer too.
