“Finally, it is worth noting that multiplicity is not necessarily the best possible option under all circumstances. For example, an entrepreneur cannot run 10 businesses at once; he must be as focused as possible and only then will he succeed. Note, however, that this applies only to the entrepreneur: the exact opposite applies to the investor. If the investor puts his whole heart and soul into a single startup and refuses to work with any others until he makes a successful exit from the first, his risk rises exponentially.”
