Can anyone else admit to having feelings of hostility towards others, and now regret those feelings?

Can you look back and see that you are less hostile now than you have been in the past? What has helped you in this regard?

It's something that I've been working on. I'd like to get to the point where I don't feel anger at all. All I have are painful memories of the times that I've been angry.

I see I'm really talking about 2 subjects. Anger and hostility. They are usually experienced together, in my case, and I'd like to get rid of both.

I can think of numerous occasions when my anger and/or hostility made the situation worse (usually by creating enemies, or just creating the desire in others to retaliate), but literally no times when it was beneficial.
