So, since I accidentally bought the lumosity subscription...l've been using it. There are little tidbits of quotes and advice from other members. Just got this one - I think DH you'll especially get something from it, cuz we both deal with this cognitive dysfunction bs (along with many other peeps obviously) and trying to work:

“Don't waste moments of cognition on negative responses when you get one wrong.”

Sounds simple but kind of an ah-ha moment for me.
