This iconic bestseller from the bestselling author of All Marketers Are Liars proves that winners are just the best quitters and 'should be on every entrepreneur's book list' (Entrepreneur.com) Every new project (or career or relationship) starts out exciting and fun. Then it gets harder and less fun, until it hits a low point - really hard, really not fun. At this point you might be in a Dip, which will get better if you keep pushing, or a Cul-de-Sac, which will never get better no matter how hard you try. The hard part is knowing the difference and acting on it.
