Just as a point of information, I always find that it is far more satisfactory to own a company, rather than simply being a member of a board, main or otherwise. Removes all requirements for such outlandish practices as due diligence and the need to keep compliant accountants in train.
Similarly, it is also by far the more sensible course to keep the company outside of public ownership, simplifies decision making, particularly in areas of finance and taxation. Allows for clean disposal of any employees at any level who start to show tendencies of entitlement.
I provide this information, purely for the guidance of any that feel overwhelmed with the responsibilities that can occur in life and, in the excessive time and effort required in considering and continually advising the world at large of their possibly dubious grandour.
