7 You are afraid of the unknown
You are worried about not knowing what will happen to you. You can drive half-a-ton of steel at sixty miles an hour inches away from other vehicles, and trust their drivers to do the same. You can purchase and eat food that you didn’t see being cooked. You can enter a convenience store after nightfall. You regularly plug and unplug cables carrying 120 volts (or 240 volts) of lethal electricity. Heck, you pipe the stuff through a pad in your bed. But changing jobs is really dangerous.
