Gravity
Life is easiest when we flow with gravity. We should resist it sparingly, and with great force.
Yet the goal is not to change gravity, but to coerce it to alter the orbit of an object.
A habit is a small, honest example. At first, you push against your nature. Then it becomes your nature.
A startup is another example. Before you find product/market fit you can feel like Atlas, holding the weight of the world on your shoulders. In constant resistance. In constant opposition. Then it clicks. The orbit is altered. And everything flows.
Learn when to flow and when to resist.
