Some good advice here.
What i usually see, when i hear the words at the top of your post is someone who is about to quit their job.... with nothing after that. No plan. No idea of what they want, where the want to be or what they want to do.
But they know step 1. "Take this job and shove it"
Unfortunately, that is not step 1, that is the next to last step.
Find what you love and go for it, that is the goal. Quitting the job is almost an afterthought.
The universe loves a vacuum. I have quit jobs with no plan before. It's just like uggggggh I cannotttt anymore. Jobs take sooooo much energy, especially when you hate them, that you don't have the energy to find another one or know what you want. Very often people need the space. I said this very same thing to a friend who promptly followed my advice and promptly got a job that she loved. She said it worked.
I see what you mean but I'm not sure if that's it for everyone. Some people are just too bogged down to even figure out what they love so in that case quitting the job would be step one. A lot of people don't get much further than that though and find themselves in a similar situation before long, but I guess no everyone is ready for the journey.
