Hi there, I'm a new writer and am seeking some advice in relation to developing a character for a screenplay I'm attempting to write, specifically regarding flaws and their relation to a character's pursuit of their goal in a story. A lot of the advice I've read about developing the protagonist character stress that you need to determine what his/her flaw and main goals are, and that their flaw should be something that he/she needs to overcome in order to achieve that goal. My question is, what if the main hindrance to the protagonist's pursuit of his/her goal is actually completely external, and unrelated to any of his/her character flaws? Would you still create flaws for that character, and let them overcome those flaws throughout their character arc (or not), while he/she is simultaneously attempt to pursue their goal? Or would they not be required? Any advice would be greatly appreciated.
