Book excerpt: Our decisions determine our lives. Invest in a company that goes bankrupt and you lose your life savings. Say the wrong thing in an interview and you miss the job of the lifetime. Make no decisions and you miss every opportunity. In today's rapidly changing world, the cost of poor decisions (and no decisions) is higher than ever. In How to Make Good Decisions Wisely, author and scholar Alan Ehler lays out a clear approach to making big decisions based on the Bible and recent discoveries in neuroscience and decision science. He presents a simple, four-step process that can be followed to make any kind of decision, whether personal, professional, or relational. Making big decisions can rewrite lives, careers, families, churches, and businesses. A lot is at stake. Learn how to choose well.
