“My biggest mistake at the job was…”
We’ve all done it — flubbed something big at work, and lived to tell the tale. Here, adults with ADHD share stories of the work goof-ups that taught them most.

If you’ve thought, “I keep making mistakes at work!” you are not alone. ADDitude gave the prompt, “My biggest mistake on the job was…” Readers share their (sometimes humorous!) responses below:
“Overpromising! When someone has a request, I now say, ‘Let me get back to you,’ and then take a few minutes to consider my availability for the task.” —Cathy, Texas
“Putting myself in charge of bookkeeping. Ugh!” —Daniel, Connecticut
“Using inappropriate words and hand gestures with my subordinates. I think we are fooling around, but some people take everything seriously. I can’t seem to get the social cues right.” —Sheri, Florida
“Mistakenly mailing one client’s document to another, and vice versa. I work for a financial-services firm, and the mis-mailed documents contained lots of personal information. What’s worse is that I didn’t know it happened until unhappy Client A called my boss. That was not a good day for me.” —Emily, North Carolina
