Massive list of character traits and flaws

Here's an extensive list of character traits. You can pick a couple or three to form the basis of a character. Then create a character with the opposite traits to form a friend, enemy, sibling, mentor ... ?

While there's a great deal to be said about nature forming our characters, it's a lot more interesting for a story if there's a background reason! :-) So ask yourself why the character developed those traits. What happened in the past, recent or childhood, that moved them in that direction. And perhaps the trait only comes out in certain situations. A low-energy character could be forceful when the one thing he cares about is threatened. A frugal character could have a massive collection of manga. Someone could dole out their compassion just to those who are trying hard and have little sympathy for those who are letting themselves be weighed down.

Pick all from one list or all from different lists or mix them up and choose completely randomly. There are plenty of positive traits that aren't normally paired together and could make for interesting characters, for example, cultured and easy going, or inept and cocky, or feisty and dainty so it isn't necessary to mix them up.

If you love lists, there's another list: Cattell's 16 Personality Factors for writers Again, feel free to pick all "Less" or all "More" factors since shy and practical, or sensitive and lively, or competitive and solitary aren't usual combinations but could make for some nicely complex characters when you dig into their lives and figure out why they've become who they are.
