What Makes a Good Liar?

What Makes a Good Liar ?....mm lets see.....Full body control, Poker face on, Clear mind, Normal behavior!
Well before I get into it, i would like to give my straight opinion about liars. To be a good Liar we to be a little insensitive to peoples feeling's .We are obviously lying to them for a reason. To me personally we have to be a tad psycho to be good, because normal people aren't so good at lying. And to be Normal and a Great Liar is diffcult because that much attention to your every move, your every thought is intense. You would have to be able to, work out anything with a little bit of information and have a good memory so you wont get caught.
