Depends on your current situation.

If you are a young professional, I think its a great step, because now you are really forced into doing/finding something you are passionate about. Or going to solve a problem you will develop a passion for.

I am currently in this situation. Didn't get a job after college. Because I prefer to be jack of all trades. This perspective helped me dive into something I really want to work on, the Enterprise space.

Now I am in a job with a big company. I am unfit because I think too entrepreneurial. But I am absorbing all the information here, and taking advantage of the position to learn about the enterprise.

I think its a calling for me to work harder, double up on developing my product on the weekend, after work.
