Best brain hack is taking “this too shall pass” and applying it in the micro. The panic you feel from an argument with a friend, wanting to get on your phone when you should be studying, the absolute obsession with someone you’re crushing on, pain from rejection, utter hopelessness at a situation that is not entirely hopeless. Heavy on situations that induce panic and incentivize you to act out of turn, maybe to send a text you shouldn’t be sending or to blow up at someone or whatever it is. The antidote to knee jerk reactions is literally just “this too shall pass” and allowing yourself to feel the physical manifestation of your extreme emotion. Literally just ride it out. Even for things that can’t immediately be resolved, it makes such a big difference and prevents you from reacting in ways that you would undoubtedly regret down the line.
