Flaws and weaknesses
Ok, so we all probably know, that its good for a character to not be perfect. It makes him/her relatable and blah, blah, blah - lets be honest, who did hear about it?
Ok, but I have a character and I m not sure if he has flaws or if he has enough flaws. He is already a complete character and I dont feel like renovating him.
Here is a magical trick.
Make flaws of his good traits by making them bigger. Example:
Jenny is very hard-working and responsible.
Those r good. How to make them not so good?
Jenny didnt answer her best friend calls in two weeks, cause she was working. Workaholic, thats who she is.
Harry is very empathetic.
Well, thats great Harry. But is it for sure?
Harry secretly cries his pillow every night, because this sad add of a charity that helps sick kids he saw week ago.
Is that good? No, Harry, its bad, that people r in pain, u can help, but u also must live ur life!
U can something like that with every trait. Its pretty useful.
