Where to start with characters?

[ShadeZ]

I cannot for the life of me work on characters to be fleshed out or even gimmicks (for D&D). Any advice? Motivations are a killer, how they react to things is difficult. Just... throw all the advice you've got at me.

Gimme a list of characters and pm if ya want and I'll run scenarios with you. (Pose situations of your character to see how they act)
