According to Osho, an inferiority complex is born from a concealed superiority claim: you secretly assume you’re the greatest, the world’s center, then fail to substantiate it in life. The gap between egoic ambition and actual performance breeds remorse, anguish, and the feeling of being nothing. Striving to assert superiority paradoxically manufactures inferiority.
If you think you must be the best but can’t prove it, you start feeling small and less than others.
