Selected Works of Mao Tse-tung
1929
Young communists and non-communists who have brought new blood and new spirit to the revolutionary ranks are precious people. Without them the ranks can never be expanded and the revolution can never be won. However, their weakness lies in a lack of experience, and experience comes only from personal participation in revolutionary struggles. The inexperienced can become experienced if they begin from the lowest level and work steadily without a grain of dishonesty for several years.
