"I'm a little commitment phobic, in that I've always been someone who likes to take things one year at a time because as we all know, a year can change everything in your life"

This quote by Debra Messing speaks to the concept of dedication phobia, or the worry of making a long-lasting commitment. Messing is revealing her own hesitancy to commit to something for an extended period of time, rather preferring to take things one year at a time. This is likely due to the reality that a year can cause a lot of modification in one's life, and Messing might watch out for making a commitment that might be impacted by such modifications. This quote is a suggestion that life is unpredictable which it is important to be conscious of the potential for modification when making decisions.
