Wrong and right

What is wrong and what is right how can we decide this ?
This question arises first when we are about to take decision but then what we do ?
Do we hear the decision which our inner soul takes ?
I think no many of us use to go with our decision which is most of the time is proved wrong ....
Then what about those who use to hear voice of their inner soul are they extremely right all the time ????
Don't know about that but yes according what we have heard it is about 85% right .....
So now the question arises that if it is like that then why we don't use to hear that voice every time why we neglect it most of the time???
Well don't know about that but I have to say that for once we should hear the voice of our soul because it comes when ever we have to take decision  or whenever we are suppose to commit a mistake ....once for sure it warn us.... and when we didn't hear it then after realizing the mistake we regret on our decision ......
Would just think at once that why we are neglecting the right and accepting the wrong .....????
