I am myself not particularly interesting, and I actually find other people finding me boring to be a good thing, most of the time, since interesting people have to talk more:), however, I know two people who are definitely different, in a good sense. Both are environmentalists, passionate about it, but otherwise very unlike.

One is kind. I have no other word for it. He's just easy to be about, has a sense of humor, makes a funny face if annoyed, sometimes boasts or exaggerates - but somehow, in a way that doesn't wound feelings, downloads tons of music, wears baggy sweaters, is a womaniser, goes to his former flames (mostly successfully married) to play with their kids, was raised by a photographer who welds things from scrap (like 'toy' ships), plays a guitar and something else, travels often, works with GIS (maps records of rare animals), can discuss legislation patiently, does not drink or swear (AFAIK), is rather sickly but quite resilient, and is just generally a person who lets others cool down.

The other is a very focused man, drives people to him by getting shit done, drives them away by careless treatment which he himself doesn't consider an issue (like, he values others' time less than his own, disregards grammar, which sometimes makes his messages impolite), attracts them back when they understand that shit still needs to get done, drinks sometimes (and has been touchingly attentive to his friends so that he'd not offend them awfully under the influence), is quite fearless when it comes to confronting superior odds (and trusts his friends to be fearless, too - a most engaging trait), waves his hands around, vies for being the leader, treats 'his people' as 'His People', shares generously, has a naive appreciation of poetry and a non-naive - of art, been to Antarctica, and generally gets under people's skins:)
