Its gonna be a tough road to change but very possible.

I think best advice I can give you is. Don't think/act with your emotions, they are just emotions to be felt, feel them. Don't dwell on your past wrongs, don't forget them or you will repeat your wrongs, just think about them from time to time. Accept the truth. You are intelligent and you are dumb, just as everyone else. There is no need to spout hatred/negativity even when someone is wrong, as you might know your mind is the greatest punisher of all and we are trapped in it. Nothing is better than something else, it can be more efficient in some ways but in others itll lack and possibly be destructive but you won't acknowledge it.

I.e: A factory is more efficient in creating products than doing it by hand, at the cost destroying earth.
