Trouble Starting a Task
Just as children with ADHD often put off doing homework, adults with ADHD often drag their feet when starting tasks that require a lot of attention. This procrastination often adds to existing problems, including marital disagreements, workplace issues, and problems with friends.
Lateness
There are many reasons for this. First, adults with ADHD are often distracted on the way to an event, maybe realizing the car needs to be washed and then noticing they’re low on gas, and before they know it an hour has gone by. People with adult ADHD also tend to underestimate how much time it takes to finish a task, whether it’s a major assignment at work or a simple home repair.
