Every day without fail one should consider himself as dead. There is a saying of the elders that goes, 'Step from under the eaves and you're a dead man. Leave the gate and the enemy is waiting.' This is not a matter of being careful. It is to consider oneself as dead beforehand.
Matters of small concern should be treated seriously.
By being impatient, matters are damaged and great works cannot be done
Light matters should be dealt with seriously. Serious matters should be dealt with lightly.
