i used to work in call center, it was not 911 life saving line, just insurance claim registration, though even it was bad pay it was sort of satisfactory to help people who experienced disaster or accident and talk them through it when they were in stress, at least i knew i calmed down some people and checked their priorities that maybe they crashed their car but they are not injured
higher i went with salary later in IT less satisfactory was the job, because in the end of the day what will be difference if there will be minor bug in mobile phone OS, i always found it funny how serious newcomers took it, they think we are saving lives by fixing crashing so under certain scenario? in this regard bakers job is much more important than mine
nowadays i just don't care, job doesn't really fulfill me, or better said i can enjoy it despite knowing it's pretty much irrelevant
if you really feel the urge to do something meaningful switch progression, those important are actually usually very easy to enter, i am seriously considering now if i should become policeman since police have trouble to find people with offered salary, it would be pretty useful job, though i guess not so good to provide for my family
