I'm on year 17 in the industry and year 5 of "care less" which has really turned into "care very little, if at all". I work for a FAANG and while I procrastinate like crazy (btw I have very bad ADHD, so factor that in), I still tend to complete my work on time or ahead of schedule. I do the bare minimum though and I don't give a damn about the job at all beyond that. I haven't put in an honest 40 hours in years. I try to cram all my real work into a 2-3 hour block of time each day. Somehow my managers are still very happy with my output and I still get offered promotions ¯\_(ツ)_/¯
My sole reason for working is to survive and provide for my family. I put most of my passion and energy into hobbies instead. All of this makes it so I don't dread work every day; it finally feels like I have equilibrium in my work-life balance now even though I still do on-call rotations and work for a massive company.
Funny thing is all of this started from me randomly finding an "e-book" called "The Gervais Principle, Or The Office According to The Office" by Venkatesh Rao. It's a somewhat exaggerated take on things, but it got me to re-evaluate my career and life. Free to read: https://www.ribbonfarm.com/2009/10/07/the-gervais-principle-...
