Unless you realise and experience a great
lost due to your foul temper - usually the motivation is there to
control, but isn't good enough. There are people who actually lose
the ones they loved because of their temper - when they regret, its
too late to reverse.
Now? Even if I were to punch them, they wouldn't hit me back, even
if it was a friendly return.
One good suggestion is to walk away when your anger started
brewing. If an argument is heating up, don't start blasting away.
Count one to ten mentally before you speak. By allow time to think,
your temper effectively reduce 50% the strength. People with foul
temper often regret the things they say, because sometimes its'
truely unpleasent, hurting and leave long lasting scars. 
Cheers
