Carefully watch your thoughts, for they become your words. Manage and watch your words, for they will become your actions. Consider and judge your actions, for they have become your habits. Acknowledge and watch your habits, for they shall become your values. Understand and embrace your values, for they become your destiny.
If you spend too much time trying to find out what is good or bad about someone else, you'll forget your own soul and end up exhausted and defeated by the energy you have wasted in judging others.
Human judgment of human actions is true and void , that is to say, first true and then void.... The judgment of the word is true, the judgment in itself is void.... Only he who is a party can really judge, but as a party he cannot judge. Hence it follows that there is no possibility of judgment in the world, only a glimmer of it.
When we do not know a person - and also when we do - we have to judge his size by the size and nature of his achievements, as compared with the achievements of others in his special line of business - there is no other way.
