I punch the wall, the pain makes me forget I'm angryor just go for a run.
Invest in a heavy bag. It's cheaper than replacing dry wall 2x a week.
I pound on a heavy bag hanging in the back yard. Nothing lets me vent like wailing on a heavy bag for 5-10 minutes. I keep my anger pent up until get home to pound away my aggression. It's cheaper than therapy and dry wall.
