Do not let your mind float like a piece of paper in the wind

Do not let your mind float like a piece of paper in the wind. Work hard to keep it focused at all times. When doing a task, think of nothing else. When walking to work, count the steps that it takes to get all the way to the office. This is not easy but your mind will soon understand that you hold its reins and not vice versa. Your mind must eventually become as still as a candle flame in a corner where there is no draft.
