Impatience

The tendency to overvalue immediate rewards and undervalue delayed ones (hyperbolic discounting). Impatience is not just a character flaw—it's a deep biological tendency calibrated for environments where the future was uncertain and short-term survival dominated. In modern contexts where compounding, long-term investments, and delayed gratification produce the highest returns, impatience is one of the most costly default behaviors.

When to use it

When evaluating any decision with a time component. When choosing between quick wins and sustained investment. When designing incentive systems that must compete with short-term alternatives.

How it can help

Explains why people under-invest in long-term assets (health, relationships, skills, compound investments) despite knowing their value. The insight is that impatience isn't irrational in an evolutionary sense—it's miscalibrated for modern timescales.
