Feel like I’m shilling a bit here, but I’ve been able to significantly reduce the amount of clutter that comes into my home every day with CC, which not only helps my mental state, but of course the environment as well. I don’t have ADHD, but I can imagine that using a service like this might be able to significantly reduce distractions and help a person stay focused on what’s important. Just wanted to share this with fellow Beehawers in case it helps. CC is a non-profit that relies on donations.
EDIT: And I’m in no way affiliated with them!
