How I will continue to function with ADHD:
Do not go to one place and end up doing something else; stay focused on one thing at a time (ie: when you’re picking up the house, don’t get distracted by a subtask, such as being reminded you need to order a book and stop what you’re doing and then go do that. If necessary, keep your list handy and write it down. Whatever happens, don’t stop what you decided to do until the time you decided to be done.)
Do curious observer on yourself and see what you’re doing as you wander about; do you want to be doing this?
Have slogans at the ready and tools to employ when you need them for various situations
