That's not the worst case though. The worst case is the possibility of ruining your finances because you have no income while trying your startup. And what if you can't find a job when you finally give up?

It's not a decision to take lightly.

Well, staying at a boring job is not very healthy to career too. The worst case is losing one's job when economy is down.

Quitting job is not the solution. Finding interesting jobs (as an employee or founder) is perhaps the solution.
