Let me see now... If I am HEAVILY invested a business deal, under what circumstances would my "focus switch" or is no longer required?
HMMMMMMMM.... The ONLY situation I would feel comfortable doing so would be if I had an iron clad partner, who was invested as heavily as me, and possessed the professional knowledge, skill, and track record to completely perform the tasks required BETTER than me!
And I seem to be drawing a Total blank at the moment of who such a partner could be.... :-)
