People who feel some overwhelming need to Change The World are basically projecting: Their "world" (internal mental landscape, personal life, whatever) is in desperate need of an overhaul. (Edit: I know because this was me, say, 20 to 30 years ago. Then I fixed my personal crap. I no longer feel like lecturing everyone else about what they "should" be doing.)

I won't even read the piece. I skimmed it. This is the closing line: You should quit your job. But, sadly, you probably won't. (It feels like a kick in the gut to even read that much.) That and the title tell me all I need to know: This individual has poor boundaries and feels entitled to screw with other people and their lives due to his dissatisfaction.

Thank you so much for not being like him. You have absolutely nothing to feel bad about (so I am glad you don't). The world would be a better place if more people were, like you, basically happy with their lives and trying to do some little things to make the world better rather than trying to promote their own Final Solution and running around lecturing people on how they should live. As a general rule of thumb, I will read things that are titled "Why I did X" and won't read things titled "Why you should do X". He knows nothing about me or my life. It is hugely egomaniacal (not to mention delusional) to presume he knows what's best for me.

Peace.
