I have always considered myself good at conversing when I really want to. Regardless of gender, looks, and the likes. My problem is that most of the time, I find people so boring after an approach. It's almost as though I can't focus because my boredom tells me, "all right, this isn't interesting. Let's move on." I start making less eye contact, my replies become short and un interesting, and I become almost zoned and bored in general. I know I have the ability to converse really well when I am genuinely motivated to exchange words. So, you can probably imagine how this can hurt my ability to converse. My question is, what is a good way for me to practice finding the motivation in me to genuinely take interest in a conversation and maintain that focus? thanks guys.

Caffiene works only to an extent. Sometimes though I usually find myself as a boring conversationalist only because I'm lacking confidence at the moment. Try role models, people who even are in movies that seem outta proportion. I use (and don't comment)

Jack Sparrow (For a tad of sarcasm and practicing hand gestures)
Tony Stark (Smart-Ass, party person)
