How much are you worth

On that last post how much I am worth, I think I should sell a 30% share and I can maintain controlling interest. Then use the 570,000(odd) to get a nice house in the burbs... Now I just gotta find a buyer...Seeing it is only 30% I retain controlling interest, but how would I give the owner(s) dividends, and what do I do if my value drops which it more than likely will..hmm... and if they own 30% and I am unconscious would they get control of me... weird questions...
Well any takers?
Peace out all.
