When in an argument, wait for the other person to stop talking then maintain eye contact and say nothing. They’ll feel the need to fill the void and keep talking after a few seconds, but this move throws them off balance and helps calm them down. Also works great with angry customers at retail jobs.

Also, when you suspect someone is lying to you. After the silence, they’ll often try to cover up the lie because they suspect you’ve figured them out.

Taking a walk every day helps improve the mood on my dopamine deprived brain.

Sometimes the person you really need to trick with psychology is yourself.
