It is not the failure of others to appreciate your abilities that should trouble you, but rather your failure to appreciate theirs.
ConfuciusThe demands that good people make are upon themselves; Those that bad people make are upon others.
ConfuciusThe superior man, when resting in safety, does not forget that danger may come. When in a state of security he does not forget the possibility of ruin. When all is orderly, he does not forget that disorder may come. Thus his person is not endangered, and his States and all their clans are preserved.
