Listen widely to remove your doubts and be careful when speaking about the rest and your mistakes will be few. See much and get rid of what is dangerous and be careful in acting on the rest and your causes for regret will be few. Speaking without fault, acting without causing regret: 'upgrading' consists in this.
ConfuciusIt is true that we shall not be able to reach perfection, but in our struggle toward it we shall strengthen our characters and give stability to our ideas, so that, whilst ever advancing calmly in the same direction, we shall be rendered capable of applying the faculties with which we have been gifted to the best possible account.
Confucius
