i also call bullshit on gary's remarks. i do agree, though, that many people use add as an excuse and claim to have it when they don't. just about everybody could claim to have add based on one or two "symptoms" but that is not how add works. i also don't think danielle's add is going to negatively affect her climbing. from what i've seen add traits are pretty useful in that realm. people with add will hyperfocus on things of interest to them, making it fairly easy to accomplish "big" things while still unable to accomlish "normal" or "everyday" things. and imho, meds should only be for the latter and can definitely be worked around.
in any case, it may not be everybody's dream, but climbing the 7 summits is an accomplishment. kudos to her having a goal, not to mention going after and getting it.
