The net is set for the fish

The following passage is taken from the beautiful book  Master of the Three Ways by Hing Ying Ming (which libraries might classify as “Eastern Philosophy”):

The net is set for the fish,
But catches the swan in its mesh.

The praying mantis covets its prey,
While the sparrow approaches from the rear.

Within one contrivance hides another;
Beyond one change, another is born.

Are wisdom and skill enough to put your hopes on?

Just a little reminder for my future self on the uncertainty of life (r-squared never is 100%).

Update: For the uninitiated, my comment on “r-squared”  above was just a little statistical quip. R-squared is a number between 0 and 1 that represents the amount of variability of a linear model, in percentage, that can be explained by the model. Anything outside of r-squared, so 1 less r-squared, is uncertainty.
