potholes

Driving a car along a potholed road is like applying brute force to solve a problem. You are going to feel the effects of the potholes. The harder you drive the solution, the more you will encounter resistance, and the more noise and dust you will throw up.

An individual walking along the same road will be able to avoid the holes effortlessly. This is like working softly softly within existing systems to solve a problem, using smaller,  more flexible mechanisms that can bend and change direction to suit.
