"Why Don't You... Cover a big cork bulletin board in bright pink felt banded with bamboo, and pin with colored thumb-tacks all your various enthusiasms as your life varies from week to week?"

Wrote Diana Vreeland, quoted in "Diana Vreeland Asks, Why Don't You.... Diana Vreeland helmed the stylish pages of BAZAAR for 25 years. During that time she penned an advice column with extravagant ideas for the modern woman. We rounded up 12 of Vreeland's most outrageous and stylish suggestions. Check back every week for new audacious advice. So, why don't you..." 

Harper's Bazaar did that round-up in 2014, and Diana Vreeland worked there from 1936 until 1962 and then at Vogue from 1962 to 1971. I got sidetracked into the topic of Diana Vreeland after blogging about the Vogue editorship passing from Anna Wintour to Chloe Malle. As I noted in the comments section to that earlier post, I had a job in the early 1970s that required me to read Vogue (among many other magazines) ever month. I was intensely aware that there had been an earlier era that was so much wilder and crazier.

But the pink bulletin board with thumbtacks seems within anyone's reach. I assume "pin with colored thumb-tacks all your various enthusiasms" means use colored thumb-tacks to pin up slips of paper upon which you've written words representing whatever you're currently feeling enthusiastic about.
