Many adults with ADD tend to be quite intuitive. Many people with ADD also have issues with self esteem which can sometimes get in the way of listening to their intuition. In my own life I honestly can't remember a time when my intuition has been wrong. If I get a funny feeling about a person there is always a reason why. This doesn't mean I have always listened to my intuition though either.
There is a difference between listening to your intuition and just acting impulsively. You can still listen to your intuition and follow the 24 Hour Rule. When you are trying to make your final choice remember the feeling you first got about this choice. What did your gut tell you? Add to that how realistic your choice would be and what type of consequences can come from it.
