It's clear to me that everyone wants to feel that what they are doing is special and close to unique. -This is not necessarily bad, but it's something that you need to be aware because it can be a misleading feeling.-The main causes I observe for underestimating other professions are:1) Your EGO2) Some jobs really have a lower barrier to entry which attracts non-skilled people3) The unknown of what other's actually doThink of this, because it's very dangerous to believe that what you do is so special.
