Finally, in SEAL training there is a bell. A brass bell that hangs in the center of the compound for all the students to see.

All you have to do to quit—is ring the bell. Ring the bell and you no longer have to wake up at 5 o’clock. Ring the bell and you no longer have to do the freezing cold swims. Ring the bell and you no longer have to do the runs, the obstacle course, the PT—and you no longer have to endure the hardships of training.

Just ring the bell.

#10. If you want to change the world don’t ever, ever ring the bell.

Sometimes you shouldn't let yourself think that ringing the bell is even an option.
