" If I could offer just one piece of inspiration, it’s this: The Dip is the reason you’re here. Whether you’re lifting weights or negotiating a sale or applying for a job or lunging for a tennis ball, you’ve made a huge investment. You’ve invested time and money and effort to get to this moment. You’ve acquired the equipment and the education and the reputation…all so you can confront this Dip, right now. The Dip is the reason you’re here. "

― Seth Godin , The Dip: A Little Book That Teaches You When to Quit (and When to Stick)
