I've been at my current company for ~4 years. Every January the upper management folks kick off the same project and every year it dies in the planning/discussion phase. Maybe one or two other "big" projects or initiatives will "start," but it's always the same: lots of meetings between the managers without the engineers or designers, lots of hype about the "big project," meetings start to get delayed, roadmaps and plans never materialize, then people stop talking about the project altogether. Sometimes I buy into the hype because I believe in the projects, other times I try to point out issues/risks. Either way the engineering team as a whole is always ignored.
What keeps me motivated is doing what I can for the people who _actually appreciate_ what I do. I work in manufacturing and spend a lot of time talking to the people on the factory floor. There's nothing better than hearing about their struggles and then a few days or weeks later coming back to them with "Hey, I heard you saying you're having an issue with X, so I made Y. Want to try it out and see if it makes things easier?" And then when they stop by my desk to say "Hey sibit Y is awesome!". That makes the job just tolerable enough to not leave.
