Grit

Grit looks at why some people keep working toward a goal long after the early excitement fades. Duckworth connects steady effort with practice, purpose, and support. I like the book because building a company worth selling takes longer than most plans admit. The harder question is knowing when effort is brave and when the facts are asking for a change. Good owners need both endurance and the ability to stop digging. Persistence is useful, but it should still listen.
