Every now and then it's a good idea to take inventory of your strengths and ensure that you are maximizing those talents. Make a list of all the things your employees have told you they appreciate about your leadership style. Go back as far as you can remember (which will be easy for some and challenging for others). This is important for long-time leaders as you may identify strengths that you are no longer using on a regular basis.
Typical leadership strengths I hear from class participants include: being a good listener, coaching with enthusiasm, setting a good example, showing sincere appreciation for a job well done, and allowing people to "spread their wings."
Now that you have your list, think about how often you are using those behaviors. Consider keeping an informal journal documenting each time you use a strength from the list you made. An example of an informal journal might be: a list of 4 or 5 positive leadership behaviors and each time you display one of those behaviors, you simply make a little check mark next to the behavior.
At the end of each week check your journal and see how you're doing. As with any talent, if you don't use it you'll lose it over time. Make a conscious effort to ensure you are consistently using your positive leadership traits.
