Never depend on the admiration of others. There is no strength in it. Personal merit cannot be derived from an external source. It is not to be found in your personal associations, nor can it be found in the regard of other people. It is a fact of life that other people, even people who love you, will not necessarily agree with your ideas, understand you, or share your enthusiasms. Grow up! Who cares what other people think about you!
Just as we see that fallow land, if rich and fertile, teems with a hundred thousand kinds of wild and useless weeds, and that to set it to work we must subject it and sow it with certain seeds for our service … so it is with minds. Unless you keep them busy with some definite subject that will bridle and control them, they throw themselves in disorder hither and yon in the vague field of imagination... And there is no mad or idle fancy that they do not bring forth in the agitation.
Michel Montaigne in The Complete Essays of Montaigne
The most effective attitude to adopt is one of supreme acceptance. The world is full of people with different characters and temperaments. We all have a dark side, a tendency to manipulate, and aggressive desires. The most dangerous types are those who repress their desires or deny the existence of them, often acting them out in the most underhanded ways. Some people have dark qualities that are especially pronounced. You cannot change such people at their core, but must merely avoid becoming their victim. You are an observer of the human comedy, and by being as tolerant as possible, you gain a much greater ability to understand people and to influence their behavior when necessary.
