When I was older and I first started working, I was obsessed with buying my first Chanel jacket. I saved up my hard-earned money, went to Barneys, and bought a little black Chanel jacket. It saw many, many job interviews and many, many events. I'm not fitting into it lately, but I still have it.
I also feel that the only thing more gratifying than working with someone who you've worked well with is working with someone new and coming up with something great.
