Begin by highlighting all the skills in your toolbox.
Next, narrow that list by noting which of the things you can do, are things you that you like to do.
Then, narrow the list one more time. Look only at the list of things you can do that you like to do, filter out and identify the things at which you excel.If you can say, "I'm really good at that" then it's likely it's speaking to your strengths or core competencies. That's a great place to start to explore your "want to do" list.
