'RIGHT' AND 'WRONG'

Is there such a thing as Loving the right person at the wrong time while having the wrong person when the time is right?

Then again as with everything else, is there even such a thing as a 'right' and a 'wrong' person?.

Do we use our head ....or heart to come to the conclusion of who is the'right' and who is the'wrong' person? 

The heart is the center of the body.........
But it beats on the left...... 

Are you telling me that it is that reason why the heart is not always right?
