One of your greatest assets is your internal motivator.
The best way to check on the health of your internal motivator is to create an environment of as much freedom as possible, then look at what you're motivated to do. Below are some possible responses when you achieve that environment.
"I dont know."
You feel glad for the freedom, but unsure about where to go from here. Your internal motivator is weak from lack of use. Chances are you've been working in order to get away from something rather than working to move toward something. Avoiding fear, such as the fear of being unable to pay bills, is a common motivation and is damaging to your internal motivator. Build your internal motivator strength by moving towards the positive instead.
When you are in a work environment that is damaging to your internal motivator, its important to recognize it and make changes.
