If you haven’t watched this week’s episode of Mad Men yet, you might not want to read any further.But if you have, you know that Peggy put in her notice at Sterling Cooper Draper Pryce.Go Peggy! It was certainly her time.Don, who used to teach Peggy so much, has been slacking. And the opportunities for Peggy at SCDP have been lacking.Taking matters into her own hands and leaving the comfort of SCDP, where her career began many years ago, shows bravery. Starting a new job is never easy.Having worked at 4 different agencies in that last 7 years, I know all too well that starting a new job is nerve-racking. In fact, I have walked home teary-eyed many times during the first few weeks of each new job. The new personalities you have to learn to relate to and the new clients you have to get a handle on can be incredibly overwhelming.But there comes a time when you have learned all you can from the people you work with. That is when it is time to surround yourself with new brilliant people to learn from.Looking back, I can pinpoint specific things I learned at every agency, and specific lessons I learned from every person. I am confident that I am more knowledgeable now than I would be had I stayed at the same agency for the past 7 years.And at my current agency, I truly believe that I am still learning something new every day, and am constantly being challenged by my bosses and coworkers. That is how I know I am in the right place at this time.In summary, I believe it is time to move on when you feel like your career is at a standstill. When you aren’t challenged anymore. Or maybe it is when you aren’t even looking, but you receive a job offer that seems like too good of an opportunity to pass up. In which case, I suggest taking the chance. As Mark Twain said, “Twenty years from now you will be more disappointed by the things that you didn’t do than by the ones you did do. So throw off the bowlines. Sail away from the safe harbor. Catch the trade winds in your sails. Explore. Dream. Discover.”Tell me, do you think Peggy made the right decision?
