Find Something to do in the Middle of This Graph.

This is not a Venn diagram. I'm assuming the activity can't be important and in your skill set and not be either relevant to your current job or interesting to you. Also, It can't be relevant to your current job and interesting without either being important or in your skill set.

Your interest and skillset are internal. Importance and relevance to your job are external. You have some control over your skillset and what your current job is. Your interest and what's important cannot be controlled. Your task is to find the middle of this graph by exploring your interests, expanding your skillset, moving toward important problems, and finding gainful employment solving them.
