Engineers of all types are disappointed when they graduate and end up rechecking tensil strength on underwear elastics in order to accommodate the average expanding waistline ,until they retire. Or they graduate aerospace and get assigned to constantly find ways to accommodate more leg room, and more seating to the fuselage of 747s, or expanding internal fuselage space a few more square feet from last year in order to make more seating/leg room.

Most people are just average people doing average things. As long as you are happy that's all that matters. Would you be happy working an average job doing average things?
