Usually there is some strong combination of ambition, motivation and interest. It may be money, prestige, pride, etc. Skilled people are driven to get to an upper level. This drive possesses them and they have difficulty understanding people that do not feel that way. They view the less skilled as less worthy.
Impatience is often a characteristic of the skilled.
They cannot understand why others are lazy or why others don't 'do what it takes'. Night school, tutors, self- instruction, etc. are not easy but they are not optional in obtaining skills. Skilled people often laugh at ignorance. They are not sympathetic. The great equalizer is that all of us were ignorant once.
