I will let you to know .. I've asked about something which "why" we need to look at problem in general way, I mean in all its possibilities and never limit the possibilities of the problem if it must be solved in general ; so imagine that you have a problem doesn't matter what it's but what is matter; it maybe has two cases "equal" and "different" .. so in general you should pick the different case to solve the problem because "different" is overwhelm the case of "equal" in other words "equal" is a concrete of "different" ......... got me?!
