I'm 48, and in the past few years, I've really grown to hate my career (I'm in IT), the jobs I've had recently, all the BS that goes along with working for other people, sitting in a cube all day, staring at a computer all day, etc, etc, etc.
I've also grown to realize that in reality, all the work I've done over my entire IT career really means nothing in the grand scheme of things. If all the work I'd done suddenly didn't exist, would anything be different? Nah, it wouldn't. Maybe if I'd worked on something as revolutionary as the iPhone, or some other such product, I'd feel differently. But the companies and products I've worked on are pretty mundane, and if they'd never existed, it wouldn't really matter.
So...for these (and other) reasons, I'm definitely ready to quit, walk out the door, and get on with the next phase of my life. I wanted to do it in 2015, but ended doing a OMY, so my new date is June 1, 2016. On that date, I don't care how well or how poorly my company stock is doing, I'm walking. I'll live under a bridge and eat cat food if I have to, but I'm walking out the door.
My stupid boss (whom I posted a separate thread about recently) wants me to do another BS dog-and-pony-show presentation to the execs this week that is just a waste of time. Instead of doing work, he wants to talk more about it. But I'm just going to bite my tongue and do the stupid presentation knowing that in 10 more months, I'm going to quit and leave my laptop and badge on his desk and walk out, and nothing's going to stop me, and there's nothing they can do about it.
Ten more months...it's like serving the last bit of a prison sentence.
