I’ve probably convinced you of the need to rely on yourself for decisions. Just in case, however, I must reiterate this point. Only you fully understand your goals and tolerance for risk. Nobody cares more about your money than you do. You worked hard for it, you searched the world for companies that meet your requirements, you became an owner of those companies, and you should count on yourself alone for the right time to sell.
