Don't Be Angry
When something pisses you off you get the urge to react, to reach out and smash. To apply violence. Or at least yell a bit.
But what if you’re wrong? Maybe there’s a misunderstanding. Maybe later you realise it’s not that big a deal. Now you’ve got to handle the fallout you’ve caused.
See if you wait, just save that reaction, hold off retaliating. Makes you emotionally solid, incredibly stable, hard as nails.
You can always be angry later.
