Really interesting. I've been on Adderall for almost 10 years and am constantly accused of being overly optimistic, which sounds a lot like the "the brain to fix its attention on the benefits, rather than the costs, of completing difficult tasks." from the first paragraph.

Are you being accused of optimism in hindsight or by naysayers in advance before attempting something? The answer matters. Sometimes accusations of optimism are a defense mechanism from lazy people. Or it could be good feedback that your projects are over-scoped.

If it's in relation to scoping work or how long it will take to do something, it may be the "time blindness" that typically accompanies ADHD. This typically leads to optimistic estimates of how much work can get done within a certain timeframe.
