Waiting For Something Just Dont Know What

I need a polite and effective way to say "hey your heart is truly in the right place and your anger is often righteous but I think sometimes you’re getting recreationally mad about things that are frankly not worth the amount of energy you’re spending on them, and every time you do this you're driving yourself slightly more insane with nothing to show for it," and then I need a way to broadcast that message through a loudspeaker to roughly 30,000 people at once, and THEN I need a time machine to send that message to my past self lol. and maybe a second time machine in case past me tries to be clever and sabotage the version of me who comes through the first time machine
