This DISC and Values Profiling Tool on Tony Robbins's site is an excellent tool for diagnosing and better understanding your behavioral styles and personality types to help identify and maximize their personal strengths. For me, it was scarily accurate and gave some very constructive feedback about actionable improvements. Completely free and a $250 value. Highly recommend this, if like 4/5s of all workers, you think your work sucks and want to find something more fulfilling for your life. Go for it!
