One test, is they drop you in a pool with your hands and legs tied.
Another test you have to run 60km carrying 150km.
When you train to be a S.E.A.L., they put you through six months of hell, with one purpose:
To make you comfortable being uncomfortable.
They have a saying, the young men and women that choose to complete one of the most grueling physical challenges in human history.
The equivalent of swimming from Cuba to Florida. And then running from there to NYC. In combat gear.
The words those survivors chant, knee deep in mud, freezing cold, and hungry, is:
The only easy day is yesterday.
The only easy day is yesterday.
The only easy day is yesterday.
