Are you not engaged and motivated by your job? You may have the power to change and begin identifying your motives, strengths, and passion to help you better understand which aspect of your job will keep you engaged and inspire higher performance.
Then create a diagram of your current job,including your job talk, noting which you do most often. Next,create a diagram of your preferred job, indicating which things you want to do more or less of and which tasks you want to add.
This chart can help you articulate what you want to do differently. Be sure to engage your supervisor in this process; assure her that you wont let your current tasks slide and that any new tasks you propose are central to the company.
