What business book has had the greatest impact on your career?

As a business owner for 17 years, the most valuable book for me has been " The E-Myth Revisited: Why Most Small Businesses Don't Work and What to Do About It," by Michael Gerber.

It taught me that I needed to set up systems so the company could run without me, and so it could run consistently every day whether I was there or not. That was a great lesson that allowed me to coach my kids' sports teams, volunteer at church during the week, and take my family on our fair share of vacations — all without having to worry (too much) about what was happening in the business.
