If you are switching jobs:
"I'm leaving behind the business" is a phrase that will require a lot of courage. When pronounced at the wrong time or in the wrong way, it can have a very negative effect on your career. You can find a job give with another corporation where the pay is higher, but you are still uncertain if that work environment will be better then the current one. After all, it is not all about the amount of money. What if you change your brain later? After all, this is simply not a straightforward decision. Of course your boss can forgive you and hire you back, but it isn't guaranteed.
