Research into workaholics who have achieved a "Work-Life Balance" found that many only achieved true fulfilment and balance after a crisis had made them completely rethink their priorities.
Health scares were high on the list. Damaged relationships were common too.
Several people who claimed to have achieved great balance had second thoughts as they analyzed their lives.
When I found those who had been successful in both their professional and personal life there were common themes. I felt these needed to be made available to others before their very success drove them towards their own personal crisis.
Another common theme which emerged from my research was how difficult people found it to meet like-minded successful people who wanted to meet socially and have some fun.
