Engaging in mindfulness implies changing what you think about, or, where your focus is. This can be therapeutic to persons who are suffer from anxiety and depression because it interrupts periods where negative thoughts dominate their consciousness and replaces them with periods where their thoughts focused on current circumstances that are generally benign or pleasant.

For persons who don't benefit from such therapy, mindfulness could mean re-focusing away from the abstract thinking that solves problems or invents or creates. Many people deliver their work product or improve their circumstances through this type of thinking. Practicing mindfulness may negatively impact them by reducing the amount of time they spend contemplating in such areas.
