I’ve written in the past about Seth Godin’s great little book The Dip. Godin says that successful people quit the right things, and they know how to fight through the dips. A local business owner closed his store earlier this month. I saw him this morning and learned that he’s been a flight attendant for more than 20 years. He was operating the store as a second job and found that it was impossible to do both. His flight attendant job offers steady pay and benefits. While it was hard to close a business in which he had invested 3 years of sweat and dreams, he made a practical choice. He knew what to quit.
