Angry at someone else?
Is it because you’re scared of losing them?
Or you’re afraid they’re better than you at something else?
Maybe your point of view differs from theirs but you haven’t had the courage to express it.
Anger arises from an underlying fear. Realise this and instead of being angry you can use the energy to figure the fear out.
I read a Buddhist saying once.
“Anger is a hot coal you hold in your hand while waiting to throw it at someone else.”
Better to use the coal to cook a meal for yourself. Or better yet, for the both of you.
