Asymmetries are certain things in your business that you can work on whereby the output (progress towards goal) is extremely disproportionate to the input (time and energy required).

The issue is most people in business spend their time on anti-asymmetrical activities such as building websites, messing around with softwares, living a crazy lifestyle, etc.

Asymmetry is leverage. Little in, lots out. If you can learn to isolate and conquer Asymmetries you will rule your market.
