The Dip

Suggests that every new project starts out as exciting and fun but then becomes more difficult until it hits a low point and is no longer enjoyable. Describes this as being either in a dip, which will get better if you continue to push, or in a cul-de sac, which will never improve no matter how hard you try. Argues that what sets successful people apart from everyone else is their ability to give up on cul-de sacs while staying motivated in dips
