Back in December, I wrote about how Jerry Seinfeld maintained perspective by keeping a photo from the Hubble telescope in the Seinfeld writing room. This week I got an email from the spouse of a professional astronomer who said her husband gets through some work days by reminding himself that astronomy doesn’t matter. “He will say, for example: ‘It’s just astronomy. We’re not saving lives here. It’s okay if we finish this tomorrow instead of today.’” I loved that.
