Never let a job steal your life.

The company you work for is not your family, you don't owe a job anything beyond the work you're being paid for.

Prioritize your well-being over misplaced loyalty, and never feel guilty about leaving a job.

Companies aren't families, they're businesses. It's a business relationship and their goal is to make money.

If they can make more money by laying you off, they will.

If you have an opportunity to better yourself, never feel guilty about taking it.
