That is precisely what the book is about – how to discover if it is time to quit, or if the difficulties you are encountering are merely a temporary “dip.” If you can relate to any of this, I recommend the book. He makes his points memorably!
We read it prayerfully – and by that I mean we read it from the perspective that success not only involves our strongest efforts, but also God’s blessing. We figure that if He blesses us, it is so we can accomplish certain goals. (In our case that would be supporting orphanages and the fight against injustice).
We have been restructuring our business to survive in today’s economy. Lots of prayer, and endless hours of work… Thankfully, it looks like for us it has been a dip – and we are pushing through to the other side.
