Book review: The Dip
Subtitled "A little book that teaches you when to quit and when to stick" by Seth Godin.
So what is the dip ? It is the strange valley after you start with something, causing that after initial quick success you will get worse before you can get better. Obstacles that you either overcome - or you quit. Seth explains that these obstacles are there for a reason - they separate those who want something badly enough from those who do not.
