Amilcar Cabral said this quote

Always remember that the people are not fighting for ideas, nor for what is in men’s minds. The people fight and accept the sacrifices demanded by the struggle in order to gain material advantages, to live better and in peace, to benefit from progress, and for the better future of their children. National liberation, the struggle against colonialism, the construction of peace, progress and independence are hollow words devoid of any significance unless they can be translated into a real improvement of living conditions.

~ Amilcar Cabral
