so do you also have the feeling that many people get cynical, jaded, tired, no longer excited about science after they have done a lot of it. some old phd students and postdocs from the many labs i've been in seem to be so. or maybe they are just stressed/exhausted at the point they make comments with such cynicism.

i'm raising this not because i recently discovered this cynicism and lethargy, but because of my discovery of enthusiasm in many scientists around me. things like science is boring but the findings are glorious and i'll be able to take the boredom are easier said than done. and only after you work and fail and struggle do you come to appreciate the enthusiasm that has somehow survived.
