People who are gifted definitely do just what I think you are saying - they blame their failures on their own personal inabilities to cultivate habits. And because they are smart, they were often able to compensate for potential ADHD symptoms throughout school and while young, and so it's often ruled out and not even considered until they are adults (and then often not considered because they "did good in school" etc.) Obviously not everyone who thinks they are gifted actually is, but talking about those that are here.

As one of those persons (tested 98th percentile on SAT in 8th grade, for example, and was in gifted or advanced classes until I just got bored of "extra work"), I think it is important to really consider this and reflect on whether or not something like ADHD could be at play and getting in the way of life goals. The rejection sensitivity dysphoria mentioned in the article, while it is not a diagnosed condition (won't find it in the DSM), does describe one of the states of mind of a lot of people with undiagnosed ADHD because of a lot of negative conditioning for many years, being told they just didn't have enough willpower to do things "right".
