Based on the idea that an individual's "brainstyle" is a particular set of gifts, this self-help book shows the reader that by understanding how the brainstyle mandates decisions, a person can deliver his or her best in any relationship. The book illustrates with case histories of people who used the brainstyle system to change their lives without changing themselves. Chapter 1 asks some personal questions to activate thought about the need for change; Chapter 2 introduces some research on what to do instead of trying to be perfect. Chapters 3 through 6 describe four core strengths, the brainstyles; Chapter 7 is a brainstyles self test. Chapter 8 tells how to apply brainstyles to create synergy in relationships with anyone anywhere; Chapter 9 provides some tools to transform an individual's relationship with him/herself, with "enemies," and with colleagues at work. Appendix A contains "Brain-Based Aptitudes"; Appendix B contains "The Brainstyle Inventory Scoring Interpretation and Discussion"; Appendix C contains "Technical Report: Construct Validation of a New Measure of Brainstyles"; Appendix D contains "Brainstyles--Myers-Briggs Relationships Report, January 1995"; Appendix E contains additional worksheets.
