Enjoy the blessing of strength while you have it and do not bewail it when it is gone, unless, forsooth, you believe that youth must lament the loss of infancy, or early manhood the passing of youth. Life's race-course is fixed; Nature has only a single path and that path is run but once, and to each stage of existence has been allotted its own appropriate quality; so that the weakness of childhood, the impetuosity of youth, the seriousness of middle life, the maturity of old age.. each bears some of Nature's fruit, which must be garnered in its own season.
An oak and a reed were arguing about their strength. When a strong wind came up, the reed avoided being uprooted by bending and leaning with the gusts of wind. But the oak stood firm and was torn up by the roots.
Never say, ‘No’, never say, ‘I cannot’, for you are infinite. Even time and space are as nothing compared with your nature. You can do anything and everything, you are almighty
If your enemy is secure at all points, be prepared for him. If he is in superior strength, evade him. If your opponent is tempermental, seek to irritate him. Pretend to be weak, that he may grow arrogant. If he is taking his ease, give him no rest. If his forces are united, separate them. If sovereign and subject are in accord, put division between them. Attack him where he is unprepared, appear where you are not expected.
A man's excellence is like that of water; It benefits all things without striving; It takes to the low places shunned by men. Water is akin to Tao. . . . In all the earth nothing weaker than water, Yet in attacking the hard, nothing superior, Nothing so certain in wearing down strength: There is no way to resist it. Note then: The weak conquer the strong, The yielding outlast the aggressors.
