Day one of my first job out of college, my boss found out that I didn't know how to enter data into Lotus 1-2-3. That's a spreadsheet—ask your parents. His mouth dropped open and he said, ‘I can't believe you got this job without knowing that”—and then walked out of the room. I went home convinced that I was going to be fired. I thought I was terrible at everything… but it turns out I was only terrible at spreadsheets.
