If you want to learn to swim jump into the water. On dry land no frame of mind is ever going to help you

Be like water making its way through cracks. Do not be assertive, but adjust to the object, and you shall find a way round or through it. If nothing within you stays rigid, outward things will disclose themselves. Empty your mind, be formless. Shapeless, like water. If you put water into a cup, it becomes the cup. You put water into a bottle and it becomes the bottle. You put it in a teapot it becomes the teapot. Now, water can flow or it can crash. Be water, my friend.

The possession of anything begins in the mind

In a hamlet or in a forest, in the deep water or on the dry land, wherever venerable persons dwell, that place is delightful.

The capacity of the land should drive decisions on density, which relies on local dispersion of waste water.

You can do this on a land treadmill but water resistance is important. If you have to walk in a pool you have to lean forward.
