The 24 hour rule can be very helpful to people with Attention Deficit Disorder. The basic idea of the 24 hour rule is to wait 24 hours before giving somebody an answer. This is especially helpful to those with Attention Deficit Disorder because of impulsivity. Quite often people with ADD give answers with out really thinking about what may be involved.
Waiting 24 hours can give people with Attention Deficit Disorder time to process what may be involved. They can also double check to see if what was asked of them might interfere with other commitments or issues in their lives. Quite often something that sounded great "at the moment" may not seem that great the next day. The 24 hour rule is also great to use when thinking about making purchases.
