Letter: Hubbard to Commodore Staff-Guardian

Self Analysis speeds up reaction time. Here's a trick. Take a dollar bill, unfolded. Have somebody hold it vertically above your hand. Open your thumb and index finger just below the lower edge of the bill. Now let your friend let go. You try to close thumb and index finger on the bill. Did you miss it, snapping after it had gone all the way through? That's very slow reaction. Did you catch it by its upper edge when it was almost gone?
That's much too slow. Did you catch it on Washington's face? That's fair. Or did you catch it on the lower edge, even before it really got started? That's the way it should be. Less accidents, greater general alertness. Well, barring actual physical damage
to hand or arm, Self Analysis will speed that up for you.
