The quality and quantity of service you render fixes your wages and determines what sort of experience you are getting.
The only constraints that you have on your income and advancement potential are those you place upon yourself. If you don’t like your position, or if you are unhappy with your salary, do something about it. What can you do to make yourself more valuable to your department or your company? What tasks have not been completed because no one has the time or the inclination to take care of them? Look around and identify things that need to be done. Don’t wait to be asked. If you make it a habit to seek out opportunities, to take on new tasks, you will increase your knowledge about the organization and become such a valued employee that your company can’t afford to lose you.
