IMO, in everything, there will be a small cohort of incredibly motivated and dedicated to always giving their all for their job, which is also their passion in life. Then there are the people who at one point had that passion^, and are now doing the work to cash in a paycheck, and will take shortcuts where possible to replace the effort they would be putting in.

^ not that this is always something to blame people for. A passion to do something you love doesn't typically translate into doing it so that you enable your employer to profit.
