Funny. I just wrote a post about the matrix lat night !!
Agree with all you say, but in many cases it's very difficult or impossible to do, especially if you have commitments like family to look after (talking about the quitting job part of your post). I fully agree about changing diet, but I'm a fine one to talk about that. I have tried ditching meat and alcohol and junk food, and I definitely feel better for it. But daily life always smacks me down and I end up choosing convenience over health.
As for energy vampires - hell yes. Avoid them like crazy. Sadly I have a few in my life in immediate family, and it's not easy to get away from them. I can only try to minimise it.
A lot to consider in what you said and I agree that anyone should try it if they can pull it off.
Ideas are in the air! About quitting a job - I think It depends on how hard you try. After several attempts, you will win.
Sure. I've been in internet marketing for years while working a day job, but haven't made it work enough to quit. But despite numerous failures I'm still at it and will never give up. It's what I want. You can never quit on your dreams.
