At work, a project could come up that both excites you and makes you uncomfortable. In your personal life, someone could push your buttons in such a way that brings something from your deep past back to life. Old feelings will come up now in a big way, and you'll be put into uncomfortable positions emotionally -- but positions that can really teach you something about yourself, if you let them.
In a personal relationship, you may be attracted to this strange feeling of emotional rawness and want to push things further, but pushing boundaries would be better reserved for a project, not a relationship. If you have something creative to work on, you can really take it far today -- you'll go places in your mind that you've never gone before. Obsessiveness is a possibility now -- another reason to try to take it easy in your personal relationships as well as at work. Take care not to scare someone away with your intensity.
