Book excerpt: Business, like any adventure, begins with a leap into the unknown Brian Tracy's first dream was of a journey. Not a leisurely drive to the beach or a weekend campout-a wide open adventure that would take him 17,000 miles from his home on Canada's Pacific Coast all the way to South Africa. His journey- a harrowing series of false starts, long days, and narrow escapes- taught him about "becoming unstoppable," not only in pursuing adventure but in daily life and business as well. The road to business success is just as exciting and dangerous and rewarding as a trek across the Sahara. Succeeding-sometimes even surviving-requires vision, courage, persistence, and the willingness to accept responsibility for your own actions. In the end, Brian's arduous trek changed his life- and his way of thinking about life and business.
