"Filling the conscious mind with ideal conceptions is a characteristic of Western theosophy, but not the confrontation with the shadow and the world of darkness. One does not become enlightened by imagining figures of light, but by making the darkness conscious." Jung
"The shadow is a moral problem that challenges the whole ego-personality, for no one can become conscious of the shadow without considerable moral effort. To become conscious of it involves recognizing the dark aspects of the personality as present and real. This act is the essential condition for any kind of self-knowledge." Jung
If you want to try shadow work too. Here is a way to start. It might (and should) take you much deeper though. Do not judge yourself, accept yourself as you are (as opposed to "who you should be") and finally look for the positive qualities it can bring into your life (because it does!).
1. What characteristics do I find annoying/irritating/frustrating on others?
2. What might others find irritating/annoying about me?
3. What would I be like if I had some of the characteristics from question #1?
4. How can I love myself with those characteristics more?
