Anything that's different from your own realm of experience as a human being whether it's driving a car or a boat or using guns anything that separates you from yourself and leads you more towards this character's existence is a big help.
I know from personal experience how damaging it can be to live with bitterness and unforgiveness. I like to say it's like taking poison and hoping your enemy will die. And it really is that harmful to us to live this way.
