Administration necessarily pre supposes the solution of numerous interrelated problems. These problems are dissimilar with regard to their significance, place in the general chain of developments and the means and time of finding a solution for them. Lenin considered that the main link, the principal problem, whose solution provides the key to all other problems, should be pinpointed in this chain of developments. “It is not enough,” he wrote, “to be a revolutionary and an adherent of socialism or a Communist in general. You must be able at each particular moment to find the particular link in the chain which you must grasp with all your might in order to hold the whole chain and to prepare firmly for the transition to the next link; the order of the links, their form, the manner in which they are linked together, the way they differ from each other in the historical chain of events, are not as simple and not as meaningless as those in an ordinary chain made by a smith.”  [202•*  He had the gift of determining the main link and concentrating the efforts of the Party and the people on it. The development of trade, industrialisation and collectivisation were the main links of Lenin’s plan of building socialism at the different stages of the implementation of that plan.
