Mental Efficiency: And Other Hints to Men and Women! An Instructional, Psychology Classic By Arnold Bennett! AAA+++

The mind can only be conquered by regular meditation, by deciding beforehand what direction its activity ought to take, and insisting that its activity takes that direction; also by never leaving it idle, undirected, masterless, to play at random like a child in the streets after dark. This is extremely difficult, but it can be done, and it is marvellously well worth doing. The fault of the epoch is the absence of meditativeness. A sagacious man will strive to correct in himself the faults of his epoch.
