Take calculated risks. That is quite different from being rash.

The best people possess a feeling for beauty, the courage to take risks, the discipline to tell the truth, the capacity for sacrifice. Ironically, their virtues make them vulnerable; they are often wounded, sometimes destroyed.

I dream, I test my dreams against my beliefs, I dare to take risks, and I execute my vision to make those dreams come true.

Be brave. Take risks. Nothing can substitute experience.

There are risks and costs to a program of action. But they are far less than the long range risks and costs of comfortable inaction.
