Sarah Jones, a 32-year-old accountant from New York, has a secret hobby: she keeps a detailed spreadsheet of every time she outperformed, outsmarted, or outshone someone else.

The spreadsheet, which she calls “receipts”, contains over 500 entries dating back to 2015, when she first started the project. Each entry has a date, a name, a category (such as work, family, friends, strangers, etc.), and a description of what she did or said that was better than the other person.

For example, one entry reads: “June 12, 2019. John Smith. Work. Corrected his mistake in the quarterly report and made him look like an idiot in front of the boss.” Another one says: “April 3, 2021. Lisa Brown. Friends. Beat her in Scrabble by 100 points and used the word ‘quixotic’.”

Sarah says she started the spreadsheet as a way to boost her self-esteem and confidence, which she felt was lacking in her life. “I always felt like I was not good enough, like I had to prove myself to everyone,” she told Yahoo News. “Keeping track of my achievements and victories helped me feel more positive and powerful.”

She also says she enjoys looking back at her spreadsheet and reliving the moments when she was better than someone else. “It’s like a diary, but more fun,” she said. “Sometimes I laugh at how stupid or clueless some people are. Other times I feel proud of how clever or skilled I am.”

However, not everyone is amused by Sarah’s spreadsheet. Her ex-boyfriend, Mark Wilson, who discovered the document on her laptop when they were dating, said he was shocked and appalled by what he saw. “She had entries about me, about how she lied to me, cheated on me, and manipulated me,” he said. “She even had a column for rating how good I was in bed. She gave me a 6 out of 10.”

Mark said he confronted Sarah about the spreadsheet and broke up with her immediately. “She didn’t even apologize or show any remorse,” he said. “She just said that I was being insecure and that I should be grateful that she dated me at all.”

Sarah admits that her spreadsheet has caused some problems in her relationships, but she says she doesn’t care what others think of her. “I’m not hurting anyone with my spreadsheet,” she said. “It’s just for me and my own satisfaction. I don’t need anyone’s approval or validation. I know I’m better than everyone else and I have the receipts to prove it.”
