The 6 Key Lessons of the Austrian School of Economics, as outlined by Ludwig von Mises:

**Subjective Value**: Value is subjective and differs from person to person.

**Spontaneous Order**: Economic order emerges spontaneously from the actions of individuals.

**Time and Uncertainty**: Economic decisions are made over time and under conditions of uncertainty.

**Marginal Analysis**: Individuals make decisions at the margin, weighing costs and benefits.

**Private Property**: Private property rights are essential for economic coordination.

**Economic Calculation**: Markets facilitate economic calculation through prices.

These principles form the foundation of Austrian economics, emphasizing individual action, entrepreneurship, and the market process.
