Attention is a lucrative resource. The white-teethed business men are aware of this, and they will do everything in their power to steal your attention away from you. They will flash colorful and stylish ads in your face as you wait for the train, they will warp your understanding of what is good and what is beautiful, they will force you to carry a black hole in your pocket. You must guard your attention carefully. You must steer it, or else it will steer you. The proper training of the attention is synonymous with the mastery of ones’ own mind and life.
