I'm early in my career and my give-a-fuck is already dry. 29 YO, been working as a manufacturing engineer for 5 years. I sell my company just enough of my energy to make me feel satisfied that I'm not a total piece of shit, and nothing more. I collect my paycheck and I spend the rest of my energy on experiences that I will cherish for the rest of my life.
I really like my job, my employer, and my boss/coworkers. I also really like working. I love learning new skills and being able to help people. I am not a lazy person, but after about 20 hours of it, I'm ready to shift my focus elsewhere. I can be very high performance for short stints. I have no problem putting in the time when there is an actual emergency that calls for it. I cannot be very high performance for 40 hours a week, week after week, year after year, and when everything is a priority, nothing is. I don't give a fuck about anything anymore.
Why anybody would go "above and beyond" or put their all into a job that is based on punching a clock doesn't compute for me. Its one thing if you're an owner, or if you're getting paid by the job where more effort equals more reward, but I show up and leave at the same time everyday and get paid the same no matter what. The work never ends. There is no reason to "get ahead". I expend minimum energy because that is what I am incentivized to do.
I'm fucking burnt. I've become resentful and it has spilled into my personal life. Corporations have gutted so many perks and have cut quality out of the products and services they offer. Everything is about the bottom line, and its really starting to show in every aspect of life. Everything is caught in regulatory capture. It seems like nothing is working towards making life better globally.
edit: Sorry for the rant. I had intentions to make this a much more thought out response rather than the emotional BS I just spewed, but that's all I had the give-a-fuck to get out right now.
