Dreams were never part of the equation for entrepreneur Simon Squibb. After leaving home at age 15, he started a landscaping business that led to another and another until becoming a multimillionaire. It was never about having a dream and now he says, he got that wrong. Squibb has become a one-man Shark Tank, investing in start-ups, helping other people understand the power of their dreams and identifying the myths that hold people back. His new book is called What's Your Dream?: Find Your Passion. Love Your Work. Build a Richer Life.
