To keep your mind steady, just let your imagination take you to places and try to create things all the time. Lots of thought experiments, none of them have to work, that's fine because they stay put. They displace all the hostile thoughts.
In my little world it doesn't matter if no one likes you or listens to you, all that matters is your thoughts cycle through and keep moving along. That's it.
I know that so many people all around me have lost the ability to restrain their emotions, they have angry outbursts and drive their cars aggressively but I'm just a boat that keeps all the troubled waters out.
