Perspective-A big thing to handle

Sometimes a question arises in my thoughts and mind that why we think too much about something which is so painful.Or why we think for illogical matters.Can't we remain in peace always.Why does erratic methodologies enters our mind,why these trust issues appear to us. Life expectations, relationship obligations, family perspective all these just crushes my mind's crust.
But has their any solutions to any of the above problems?
Mysterious is the answer as it could have or haven't have the same. People's perspective is according to their atmosphere.The round it revolves the more it appears.One can have difference of opinion due to which they didn't get the answer soon, but one can also have an another Outlook for everything, maybe this is the reason why some are successful, while some are not.
If we discuss then this is a never ending topic but being a human mind we always wanted to explore much & much. It could be possible that view point will be based on negative or positive perspective & attitude and this is a reason that suggest what our life is & where it will be. 
It's all about the perspective of human mind, so develop a sense of the same and live life as you want. Don't indulge yourself in something which may result in losing your path, so find a correct way and act accordingly.
