Economics is not about things and tangible material objects; it is about men, their meanings and actions.
Ludwig von MisesAn entrepreneur cannot be trained. A man becomes and entrepreneur by seizing an opportunity and filling the gap. No special education is required for such a display of keen judgment, foresight, and energy.
Ludwig von MisesHe who acts under an emotional impulse also acts. What distinguishes an emotional action from other actions is the valuation of input and output. Emotions disarrange valuations. Inflamed with passion, man sees the goal as more desirable and the price he has to pay for it as less burdensome than he would in cool deliberation.
