Plant Imprints in Your Mind
An athlete trains muscles to excel in her discipline. If the discipline is sprinting she will train her thighs. If your discipline is your mind then you train your mind. Training the mind means making it lean and reason quickly and correctly. Physically our brains work by activating neurons in the nodes of our nerve network. Improving decision can be seen as improving the brains way to connect neurons.
In order to be able to take quick and good decisions good paths of thinking have to be well prepared.
