मुझे इतना गुस्सा क्यों आता है??

whats the reason of anger? when you don't get the things done in the manner, no matter its right or wrong, we tend to build anger..and in our anger we almost leave our senses unused..and the worst could be that we hurt ourselves or even damage things...
and do you think any technique can reduce it??one can only avoid situations which arise anger..
for example...right now suppose..i m in peak of my anger..and i try to count 1-10
1 2 3 4.....aah forget it!!
anger is definitely a wrong side of personality of most of us..but what if we get violent in the anger...its no doubt that we know that we are doing wrong and will regret doing it later...but all this is after the scene is over..how can i control my anger when i m angry..so that i don't trouble people much with my anger and frustration...
so i thought upon it..may be i should keep myself occupied all the time so that i don't get the time for destructive ideas..may be i should change my way of thinking all over...
but obviously i want to change myself..my anger...and don't want to hurt people for whom i care for..neither i want to hurt  myself..
so if anyone of u can help me..please do that!!
