Passion is needed for any great work, and for the revolution, passion and audacity are required in big doses.

The true revolutionary is guided by a great feeling of love. It is impossible to think of a genuine revolutionary lacking this quality.

I had a project for my life which involved 10 years of wandering, then some years of medical studies and, if any time was left, the great adventure of physics.

The revolution is not an apple that falls when it is ripe. You have to make it fall.

Remember that the revolution is what is important, and each one of us, alone, is worth nothing.

'It is not just a simple game, it is a weapon of the revolution.'
