Taylor Swift is on the cover of\u00a0Elle today,\u00a0where, in lieu of a standard interview, the 29-year-old songwriter\u00a0was invited to compose a list of 30 things she's learned before age 30.\u00a0Most seriously, she reveals that her mom's cancer has returned, but otherwise she dispenses age-appropriate wisdom, such as to stop\u00a0seeking\u00a0social media validation and "stop hating every ounce of fat on my body." Other\u00a0tidbits are the type\u00a0of information it's only possible to miss\u00a0by becoming Taylor Swift ("Recently I discovered Command tape"). Then we come to Lesson Nine, which reads: I learned how to make some easy cocktails like Pimm\u2019s cups, Aperol spritzes, Old-Fashioneds, and Mojitos because\u20262016. One reason Swift may have learned to make cocktails in 2016 is\u00a0because\u00a0she was constantly hosting parties. As she writes elsewhere\u00a0in the\u00a0list, "In my twenties I found myself surrounded by girls who wanted to be my friend. So I shouted it from the rooftops\u00a0...\u00a0without realizing that other people might still feel the way I did when I felt so alone." Another possible reason is: In 2016, when Swift\u00a0was asked on video to name her favorite cocktail, she\u00a0could only produce the\u00a0grimly low-calorie non-cocktail answer "vodka Diet Coke," for which she was\u00a0then\u00a0roasted on Deadspin. The\u00a0best revenge is living well, and\u00a0Taylor Swift has learned to\u00a0do\u00a0so with an easy\u00a0homemade Aperol spritz in hand.
