no power of the mind more susceptible to training than is attention
While attention is no doubt partly a natural gift, yet there is probably
no power of the mind more susceptible to training than is attention. And
with attention, as with every other power of body and mind, the secret
of its development lies in its use. Stated briefly, the only way to
train attention is by attending. No amount of theorizing or resolving
can take the place of practice in the actual process of attending.
