It's a problem tying one's self worth into one's job.
I think if you can work for yourself
successfully, you'll find working all that much more rewarding. When you work for someone else, not so much. A lot of people don't have what it takes to create a business and make it successful. Or they just don't want to be bothered with the hassle.
I worked for others as an employee for 45 years. I enjoyed some places I worked, but hated others. Today it's becoming more difficult, because long term employment is becoming a thing of the past. We have become a nation of short term job hoppers, and it's becoming much less rewarding. Globalization is also hurting people in finding work for good pay. Honestly, I was glad to get out when I did, (Dec. 2014).
I've never looked back. I enjoy life a lot more. And it's about as stress free as it can get. So as long as I'm lucky enough to remain reasonably healthy, I can't complain.
