How can one be correct?

How can you make sure that what you did is correct? On what factors can we say that what we've done is correct?
     What I feel is, whatever you do is correct. Its just that everybody have their own perspective. Do you think lying is wrong? well it depends upon what context its been used or at which situation its been used.

You might do something to benefit others. But its not always that they think that what you did for them was correct for them. They have their perspective.. and you have yours.. This is the main reason why people dont make close friends as and when they grow up.
